Change 5 - 2 into an addition problem using a change in sign and the additive inverse. (Step 1: change the minus sign to a plus sign. Step 2: change the second number in the

problem to its opposite (additive inverse].)

What is the axis of symmetry of the function f(x)=-(x+ 9)(x-21)

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.
