What is the average rate of change for this quadratic function for the interval from x=3 to x = 5?
A. 16
B. 8
C. -16
D. -8

(D) -8

Step-by-step explanation:

Rate of change = dy/dx = ∆y/∆x

Therefore, Rate of change for interval x=3 to x=5 is :

∆y/∆x = (-26+10)/(5-3) = -16/2 = -8

the answer is stop cheating on things stoopid

step-by-step explanation:

im eatin up the 44

i think that you should ask google for the answer to that problem because if we don't know it google does
