If line r represents f(x)=x-4/3. Therefore, that line represents f-1 is __ and f-1(x) = __x+__.

f(x) = x² + 2x - 4

g(x) = 3x + 1

f(g(x)) = f(3x + 1)

f(3x + 1) = [3x + 1]² + 2[3x + 1] - 4

= 9x² + 6x + 1 + 6x + 2 - 4

= 9x² + 12x -1

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
