If f(x) = 1-x and g(x) = 1+x, find fg(-1)
You asked:
Given the following function definitions: \[\begin{aligned}f\left( x \right) &= 1 - x\\ g\left( x \right) &= 1 + x\end{aligned}\] Evaluate \(f \cdot g\left( -1 \right)\).
MathBot Answer:
$$\begin{aligned}f \cdot g\left( -1 \right)&=0\end{aligned}$$
$$\begin{aligned}f \cdot g\left( -1 \right)&=f \left(1 + -1\right)\\f \cdot g\left( -1 \right)&=f 0\\f \cdot g\left( -1 \right)&=0\\\end{aligned}$$
