Question

The graph shows the function f(x). which value is closest to the average rate of change from x=1 and x=4? a. -0.5 b. -1.5 c. -0.8 d. -0.4

can someone please me with this

Answer 1

c. -0.8

Explanation:

From this graph, I estimated the values for the following ordered pairs (1, -2.5) and (4, -4.75)

We can set up the equation for the average rate of change like this

`(-4.75-(-2.5))/(4-1)`

This simplifies to

`(-2.25)/(3)`

Which simplifies further to

`-0.75`

This is closes to c. -0.8
