Question

Given the equation f(x) = -2x^2 + 4x + 6, find the average rate of change from x = 1 and x = 2

Answer 1

-2

Explanation:

Average rate of change is another term for average slope, and is found with the equation

`(y_(2)-y_(1) )/(x_(2)-x_(2) )`

The first point is (1, 8). The second point is (2,6).

`m=(8-6)/(1-2) \\m=-2`
