Question

For the graphed function f(x) = −(3)x − 1 + 3, calculate the average rate of change from x = 1 to x = 3.

Answer 1

So basically x1=1 and x2 =3
So you have two points
(1,0)
And
(3,0)
Since there was no y that was given we simply let y be zero. You plug the points into the equation and the. The formula would be
F(x2)-f(x1) divide it by the value of
X2-X1
