Question

let f(x)=-2x+4 and g(x)=-6x-7. find f(x)-g(x)

Answer 1

Here's an example of this.

f(x) = 7 and g(x) = 4, find f(x) - g(x)
answer:

f(x) - g(x) = 7 - 4 = 3

Just replace what you know f(x) and g(x) to be and then simplify.

Answer 2

i got 4x+11

Answer 3

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