What is the average rate of change for this exponential function for the interval from x = 2 to x = 4? A. 120 B. 256 C. 2 D. 12

a

b

d

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
