Question

Use the graph below to answer the following question:

What is the average rate of change from x = −4 to x = 1?
A.-3
B.-1
C.0
D.1

Answer 1

Answer:

The answer is B.-1

Step-by-step:

When you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. f(x) = x2 and f(x + h) = (x + h)2 Therefore, the slope of the secant line between any two points on this function is 2x + h.p explanation:
