Question

Which is the best estimate for the average rate of change for the quadratic function graph on the interval -8

The less than symbol is supposed to have a line under it but I didn’t have that symbol like shown in the picture


A) -1

B)-2

C) 1

D) 2

Answer 1

x1= - 8, y1= -12
x2=-4, y2≈1

Average rate of change=(y2-y1)/(x2-x1)= (1+12)/(-4-(-8))=13/12≈1

Answer C) 1.
