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

range is infinite on both x and y axis positive and negative

step-by-step explanation:

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
