The highest common factor is 7:
49=7*7
84=7*12
91=7*13
We want h(x) = g(x) - f(x).
h(x) = -2x + 9 -(6x - 5)
h(x) = -2x + 9 -6x + 5
h(x) = -8x + 14
The first part of the answer is 20x+9
Second part is 4a-6b

Answer:
f(g(x)) = -3x^2 -2x -3
Step-by-step explanation:
<u>Given</u>:
f(x) = -x-7
g(x) = 3x^2 +2x -4
<u>Find</u>:
f(g(x))
<u>Solution</u>:
Substitute per the function definitions.
f(g(x)) = f(3x^2 +2x -4) = -(3x^2 +2x -4) -7
f(g(x)) = -3x^2 -2x -3
