What is an approximate average rate of change of the graph from x = 12 to x = 15, and what does this rate represent? (4 points)

first of all, i would put it in an equation. then i would slove that and use that answer.

Step-by-step explanation:  

use the equation 12X x 15 = y

12x=15

12     12

x= 180

14

step-by-step explanation:

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
