F(x) = 8x2 – 2x + 3
g(x) = 12x2 + 4x – 3
what is h(x) = f(x) – g(x)?
options:
h(x) = 20x2 + 2x
h(x) = –4x2 – 6x
h(x) = –4x2 – 6x + 6
h(x) = –4x2 + 2x

Correct option is (C).

Step-by-step explanation:

Now,

h (x) =f (x) - g (x)

So, correct option is (C).

Step-by-step explanation:

Given functions :  (1)

  (2)

To find :  

Consider :

i.e. Subtract the expression for g(x) in equation (2) from the expression for f(x) in (1), we get

Multiply (-) sign inside the parentheses, we get

Combine like terms, we get

Hence, the correct answer is
