Graph Of The Cubic Function
The cubic function can have one or three real zeros. Each zero corresponds to a point in the x-axis where the value of y is zero. When the coefficient of the cubic term is positive, the function is increasing, then decreasing and finally increasing.
The given function is
f(x)=(x - 3)(x - 1)(x + 1)
There are no options to choose from but I'm including a graph with a plot of f(x) plus the table of values to improve the sketch with more details. The zeros, maximum and minimum values can be clearly seen
Answer with step-by-step explanation:
The way the question is worded, this actually shouldn't be correct. The correct answer should be .
Because the trapezoids are similar, we can find the ratio of their perimeters by actually just finding the ratio of their sides.
Why?
By definition, the corresponding sides of a polygon are in a constant proportion. The perimeter is simply the sum of all sides of the polygon. Since we're just adding the sides, the proportion will still be maintained.
Therefore, we'll just need to ratio of their corresponding sides. The only two corresponding sides that are marked are and .
The ratio of is .
The reason why it ideally should be and not is because the question states , which mentions first, so our answer should follow this respective order. I believe you were marked right anyways because the specific order is not specified, but generally, you want to give your answer respectively by default.
Answer:
Step-by-step explanation:
if a is less than zero then b will from 4 down to negative infinity
so b < 4
Does this help at all? ask me some questions if you really want to learn about math ;)
Answer:D
Step-by-step explanation: the equation is written is slope- intersect form were -2 is the y intersect. the coordinate of the y intersect is (0,-2). the number in front of the x is the slope which is 1/2. so the answer is D.
Answer:
Step-by-step explanation:
Looking at the graph
For x=-2 ---> f(x)=3
For x=2 ---> f(x)=1
so
we have the points
(-2,3) and (2,1)
Find the slope
The equation of the line in slope-intercept form is equal to
we have
---> see the graph
