Question

For which function is the average rate of change over the interval 1 < x < 5 greater than the average rate of change over the same interval for the function g(x) = 1.8x2?
A. f(x) = x2 B. g(x) = 1.2x2 C. h(x) = 1.5x2 D. k(x) = 2x2

Answer 1

Smallest coefficient of x would have greater rate of change

• f(x)=x^2 is correct (Green one)
