Question

find the average rate of change of f (x)=-2x^2+4
A) from 0 to 2
B) from 1 to 3
C) from 1 to 4

Answer 1

average rate of change is equal to change of y/ change of x. so get the pairs of coordinates at (x=0, y=?) (x=2, y=?)

Answer 2

then you can do change of y/ change of x.

Answer 3

i dont understand. @katherine.ok
