Question

What is the equation for f(-x)

Answer 1

f(-x) = -2x^2 - 6x -1 - The fourth answer.

Explanation:

If we have f(x), to find f(a), we replace x by a.

Here, to find f(-x), we will replace x in f(x) by -x and we have f(-x).

f(x)= -2x^2 + 6x -1

Then f(-x)= -2 * (-x)^2 + 6* (-x) -1

f(-x) = -2x^2 - 6x -1 is the answer.
