What are the coordinates of the vertex of the function f(x)=x2+10x-3? (-5, -28)
(-5, 28)
(5,-28)
(5, 28)

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.
