Question

If f(x)=2x^2-4x-3and G(x)=2x^2-16,findf(x)+g(x)

Answer 1

`f(x)+g(x)=4x^(2)-4x-19`

Explanation:

Replace both functions in the operation as follows:

`f(x)+g(x)=(2x^(2) -4x-3)+(2x^(2) -16)\\ f(x)+g(x)=2x^(2) -4x-3+2x^(2) -16\\Reorganize\\f(x)+g(x)=2x^(2)+2x^(2) -4x-3-16\\Solve\\f(x)+g(x)=4x^(2)-4x-19`
