75 points and ! given the function g(x) = 4(3)x, section a is from x = 1 to x = 2 and section b is from x = 3 to x = 4. part a: find the average rate of change of each section. part b: how many times greater is the average rate of change of section b than section a? explain why one rate of change is greater than the other.

The average rate of each is 12 because if you calculate the slope of the points it equals 12.

F(x) = (x+1)² - 3

graph a - incorrect
x = 1
f(1) = (1+1)² - 3
f(1) = 2² - 3
f(1) = 4 -3 
f(1) = 1
(1,1)

graph b - 
x = -3
f(-3) = (-3+1)² - 3
f(-3) = -2² - 3
f(-3) = 4-3
f(-3) = 1
(-3,1)

graph c
x = -1
f(-1) = (-1+1)² - 3
f(-1) = 0² - 3
f(-1) = -3
(-1,-3)

graph d - incorrect
x = 3
f(3) = (3+1)² - 3
f(3) = 4² - 3
f(3) = 16 - 3
f(3) = 13
(3,13)

either b or c can be sanjay's because they were graphed correctly.
