Answer:
Step-by-step explanation:
The diagram shows lines passing through the points of two equations.
We will determine the points through which the lines pass through on the graphs.
Looking at the line on the right hand side of the graph, the slope is
(y2-y1)/x(2-x1) where
y2= 0, y1 = 4
x2 = 3, x1=0
Slope, m = (0-4)/3-0
Slope = -4/3
Recall the equation of a straight line is y = mx + c
Where c is the intercept.
So the equation is y
y = -4x/3 + 4
Looking at the line on the left hand side of the graph, the slope is
(y2-y1)/x(2-x1) where
y2= 0, y1 = 2
x2 = -1, x1 =0
Slope, m = (0-2)/-1-0
Slope = -2/-1 = 2
Applying equation of a straight line is y = mx + c
The equation
y = 2x + 2
So the equations are
-4x/3 + 4. If x lesser than or equal 0
2x + 2. If x greater than 0
Answer:
It’s either 1 or 2
Step-by-step explanation:
C should be the correct answer.
Answer:
A
Step-by-step explanation:
First, the definition of a floor function is that you round down, whereas for a ceiling function, you round up no matter what.
So, since C and D have the definitions totally wrong inherently, we can eliminate those.
Looking at the graph, we see that all the segments have their leftmost circle filled in. This indicates that the smaller number is counted. So, it's a floor function graph.
Thus, the answer is A.
Hope this helps!
