How do I go about this? I need help.

Using the model from the previous question, complete the following. a. Given that g(x) = 4 . f(x) + 12.5 and f(x) = 17 - 8x, write the formula defining function g. g (x) =(x-10)^2-40 Preview b. Given that j(a) = - h(x) - 38 and h(a) = 4x3 - 6x + 2, write the formula defining function j. j(x) =(x-5)/30 Preview Submit
