For the miniature roller coaster ride, the minimum height is 30 inches and the maximum height is 48 inches. write and solve an absolute value equation that has these minimum and maximum heights as its solutions.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
