Question

Please help! I will medal and fan.

Find (f-g)(x):

Answer 1

Find (f-g)(x):
\[f(x)=x^{2}-4; g(x)=x+2\]

Answer 2

hint:
by definition, we have:
\[\left( {f - g} \right)\left( x \right) = f\left( x \right) - g\left( x \right) = ...?\]

Answer 3

Okay, So, (I'm sorry. I have no clue how to figure this question out.) I would get the sum of f(x) and g(x) and subtract them?

Answer 4

we have to replace teh definitions of \(f(x)\) and \(g(x)\), in such formula above:
\[\Large \begin{gathered}
\left( {f - g} \right)\left( x \right) = f\left( x \right) - g\left( x \right) = \hfill \\
\hfill \\
= \left( {{x^2} - 4} \right) - \left( {x + 2} \right) = ...? \hfill \\
\end{gathered} \]

Answer 5

Answer 6

\[x ^{2}-x-6\]
If I'm correct.
