Question

The table shows the values of a function f(x).

Answer 1

Answer:

The answer is -80

Step-by-step explanation:

The average rate of change is also the slope from the endpoints. The two points are (0,500) to (5, 100). To find the average rate of change between those points, use the formula: change of y over the change of x.

$\frac{y2-y1}{x2-x1}$

$\frac{100-500}{5-0} = \frac{-400}{5} =-80$
