Question

Determine whether the function is linear or quadratic. Identify the quadratic, linear, and constant terms.

Answer 1

B. Quadratic Function

Quadratic Term: 15x^2

Linear Term: 9x

Constant Term: -6

Explanation:

1. F.O.I.L (firsts, outers, inners, lasts) the function

BREAK APART: 3x(5x - 2) and 3(5x - 2)

(fx) = 15x^2 - 6x + 15x - 6

f(x) = 15x^2 + 9x - 6

There is a square in the function, therefore it is quadratic. The quadratic term is the term being squared, and you go from there.
