Algebraically show that each of the given combinations are equivalent to the given functions. f(x) – g() is equivalent to m(x) given:
f(0)
= - 3x + 5; g(x)
- 5x – 7; m(x) = 2x + 12
f(x) – g(x) = (
=
Is f(x) – g(x) equivalent to m(x)? yes

--- True

Step-by-step explanation:

Given

Solving (a):

From the given parameters, we have:

So:

Collect like terms

Solving (b) m(x) = f(x) = g(x)?

In (a), we have:

And

--- given

By comparison:

answer: it's a
