Answer:
Part 1) The graph has three (3) x-intercepts and has one (1) y-intercept
Part 2) The y-value of the minimum point is -3
Part 3) f(4)=3
Part 4) f(0)=3
Part 5) f(5)=1.5
Part 6) x=-6
Part 7) The horizontal line y=-1 intersects the graph three times
Part 8) The value of the function for f(6) is equal to zero
Part 9) The function is increasing on the interval (-6,-2) and (8,11) and the function is decreasing on the interval (2,8)
Part 10) The function is positive on the interval (-3,6) and (10,11) and is negative on the interval (-6,-3) and (6,10)
Step-by-step explanation:
Part 1) Find the number of x-intercepts and y-intercepts of the graph
we know that
The<u> x-intercepts</u> are the values of x when the value of y (the function) is equal to zero
Look at the graph
The graph has 3 x-intercepts
The x-intercepts are the points (-3,0), (6,0) and (10,0)
The<u> y-intercepts</u> are the values of y when the value of x is equal to zero
Look at the graph
The graph has 1 y-intercept
The y-intercept is the point (0,3)
Part 2) The y value of the minimum point on the graph is?
we know that
Look at the picture
The minimum point is (-6,-3)
therefore
The y-value of the minimum point is -3
Part 3) f(4) is equal to?
we know that
f(4) is the value of the function when the value of x is equal to 4
Look at the graph
For x=4
The value of the function is equal to y=3
therefore
f(4)=3
Part 4) f(0) is equal to?
we know that
f(0) is the value of the function when the value of x is equal to 0
Look at the graph
For x=0
The value of the function is equal to y=3
therefore
f(0)=3
Part 5) f(5) is equal to?
we know that
f(5) is the value of the function when the value of x is equal to 5
Look at the graph
For x=5
The value of the function is about y=1.5 (see the attached figure)
therefore
f(5)=1.5
Part 6) The value of x when f(x)= -3 is?
Look at the graph
we have the point (-6,-3)
when the value of f(x)=-3
the value of x is equal to x=-6
Part 7) The horizontal line y = -1 intersects the graph _____ times?
Look at the graph
The horizontal line y=-1 intersects the graph three times (see the attached figure)
Part 8) f(6) is positive or negative?
Look at the graph
we have the point (6,0)
For x=6
The value of the function is equal to zero
Part 9) Is the graph increasing or decreasing on the interval -6?
Look at the graph
The function is increasing on the interval (-6,-2) and (8,11) and the function is decreasing on the interval (2,8)
Part 10) Is the graph positive or negative on the interval 6
Look at the graph
The function is positive (f(x) > 0) on the interval (-3,6) and (10,11) and is negative (f(x) < 0) on the interval (-6,-3) and (6,10)
Solution
Find the y-intercept for following equation:
Using the slope equation formular:
The value of y when x = 0
Hence the answer is - 1
Answer:
a) There are 9 outcomes.
b) **i have attached the tree diagram**
c) 1/9
d) 1/9
Step-by-step explanation:
Both events (choosing a shirt and choosing pants) are not mutually exclusive (disjoint). Meaning that both events can occur at the same time.
a) For a sequence of two events in which the first event can occur <em>m</em> ways and the second event can occur <em>n</em> ways, the events together can occur a total of <em>m</em> • <em>n</em> ways. So for this problem, you would do 3 • 3 which equals 9.
b) **tree diagram is attached**
c) Because there are two different events occurring (choosing a shirt and choosing pants) you need to multiply using the Multiplication Rule for Independent Events : P(A and B) = P(A) * P(B)
The probability of event A occurring (choosing a red shirt) is 1/3 and the probability of event B occurring (choosing brown pants) is also 1/3.
1/3 * 1/3 = 1/9
d) You would do the same thing here as part c.
The probability of event A occurring (choosing a blue shirt) is 1/3 and the probability of event B occurring (choosing blue pants) is again 1/3.
1/3 * 1/3 = 1/9

Vertex<em> </em>is at
<em>y-intercept</em> is 3.
The parabola <em>opens up</em>.
Step-by-step explanation:
The graph of the equation is hereby attached in the answer area.
Vertex is the point on the parabola where the graph crosses its axis of symmetry. The axis of symmetry here(), is shown with the dotted line in the graph attached.
<em>y-intercept </em>is defined as the value of y where the graph crosses the y-axis. In other words, when . Putting
And, the graph opens up as shown the graph figure as well. It is also evident from the co-efficient of in the given equation
. Here, co-efficient of
So, vertex<em> </em>is at
<em>y-intercept</em> is 3.
The parabola <em>opens up</em>.
