Question

Let f(x) = -2x + 4 and g(x) = -6x - 7. Find f(x) - g(x).

can anybody help me with this? show your work if you can too, please!

Answer 1

f(x) -g(x) = 4x +11

Explanation:

Substitute the given expressions and simplify.

f(x) -g(x) = (-2x+4) -(-6x-7)

Eliminating parentheses, we get ...

f(x) -g(x) = -2x +4 +6x +7 = (-2+6)x +(4 +7) . . . . combining like terms

f(x) -g(x) = 4x +11
