You asked:

Given the following function definitions: \[\begin{aligned}f\left( x \right) &= 4 x - 5\\ g\left( x \right) &= 2 x + 3\end{aligned}\] Evaluate \(f\left( 1 \right) \cdot g\left( 5 \right)\).

MathBot Answer:

$$\begin{aligned}f\left( 1 \right) \cdot g\left( 5 \right)&=-13\end{aligned}$$

$$\begin{aligned}f\left( 1 \right) \cdot g\left( 5 \right)&=\left(-5 + 4 \cdot 1\right) \left(3 + 2 \cdot 5\right)\\f\left( 1 \right) \cdot g\left( 5 \right)&=\left(-5 + 4\right) \left(3 + 2 \cdot 5\right)\\f\left( 1 \right) \cdot g\left( 5 \right)&=\left(-1\right) \left(3 + 2 \cdot 5\right)\\f\left( 1 \right) \cdot g\left( 5 \right)&=\left(-1\right) \left(3 + 10\right)\\f\left( 1 \right) \cdot g\left( 5 \right)&=\left(-1\right) 13\\f\left( 1 \right) \cdot g\left( 5 \right)&=-13\\\end{aligned}$$
