B because a turning point of the graph means the valley or the top of a period of graph, the slope of the tangent line of which turn from negative to positive or from positive to negative.
The answer is D. because first you got solve the problem.
y=2.5x
(turn y to 0)
0= 2.5x
÷2.5 ÷2.5
_________
0=x
So we got one answer (0,0)
y=2.5x
(turn x to 0)
y= 2.5(0)
y=2.5
(2.5, 0)
When you do (0,0) (2.5,0) on the graph it will look like D.)
Answer:
(f∘g)(x)=(2x+7)^3
Step-by-step explanation:
substitute g(x) in f(x)
(f∘g)(x)=f(g(x))=f(2x+7)=(2x+7)^3=(2x+7)^3
Answer:
3
Step-by-step explanation:
Part A:
Consider from x = -5 to x = -4, they are 1 unit apart and the difference of their outputs is given by:
-3 - (-11) = -3 + 11 = 8.
Thus, the value of the output increases by 8 units for each one unit increase in the input.
Part B:
Consider from x = -3 to x = -1, they are 2 units apart and the difference of their outputs is given by:
21 - 5 = 16.
Thus, the value of the output increases by 16 units for each two units increase in the input.
Part C:
Consider from x = 0 to x = 3, they are 3 units apart and the difference of their outputs is given by:
53 - 29 = 24.
Thus, the value of the output increases by 24 units for each three units increase in the input.
Part D:
It can be noticed that the ratio difference in the outputs to the input intervals are equal for all the given input intervals.
i.e 8 / 1 = 16 / 2 = 24 / 3.
