Evaluate
\(\dfrac{f(5)+g(1)}{f(6)-g(-2)}\)
where \(f(x)=x-4\) and \(g(x)=3x+6\)
f(5) = 5 - 4 = 1
g(1) = 3 1 + 6 = 3 + 6 = 9
f(6) = 6 - 4 = 2
g(-2) = 3 (-2) + 6 = -6 + 6 = 0
So,
\(\dfrac{f(5)+g(1)}{f(6)-g(-2)}\\\\\\ =\dfrac{1+9}{2-0}\\\\\\ =\dfrac{10}{2}\)
\(=5\quad\longleftarrow\quad\textsf{this is the answer.}\)
I hope this helps. =)
