Perform the indicated operations with the following two functions.

Question

f(x)=x2 +7x-4 and g(x)=3x-12

3. f(x) + g(x)
4. f(x), g(x)≠ 0 g(x)

thanks for the help!

Answer 1

3. F(x)+g(x)=(x^2 + 7x - 4) + (3x - 12)
= X^2 + 10x - 16.

4. F(x) * g(x)=(x^2 + 7x - 4)(3x - 12) =
Multiply and combine like-terms.
