f(x) = 2x. and g(x) = x-8. find fg(5)
You asked:
Given the following function definitions: \[\begin{aligned}f\left( x \right) &= 2 x\\ g\left( x \right) &= x - 8\end{aligned}\] Evaluate \(f \cdot g\left( 5 \right)\).
MathBot Answer:
$$\begin{aligned}f \cdot g\left( 5 \right)&=- 3 f\end{aligned}$$
$$\begin{aligned}f \cdot g\left( 5 \right)&=f \left(-8 + 5\right)\\f \cdot g\left( 5 \right)&=- 3 f\\\end{aligned}$$
