Question

HELP ASAP:

The graph of a function g is shown below.
Use the graph of the function to find its average rate of change from x=-1 to x=3.
Simplify your answer as much as possible.

Answer 1

Explanation:

the rate of change (like the slope for a line) is expressed by y/x.

for x = -1 we get y = -3

for x = 3 we get y = 5

so, while x changes by 4 units (-1 to +3), y changes by 8 units (-3 to +5).

so, the average change rate in that interval is 8/4 = 2/1 = 2
