Given f(x) = -3x + 7 and g(x) = 2x^2 - 8, find g(f(x))
You asked:
Given the following function definitions: \[\begin{aligned}f\left( x \right) &= -\left( 3 x \right) + 7\\ g\left( x \right) &= 2 \cdot {x}^{2} - 8\end{aligned}\] Evaluate \(g\left( f\left( x \right) \right)\).
MathBot Answer:
$$\begin{aligned}g\left( f\left( x \right) \right)&=18 x^{2} - 84 x + 90\end{aligned}$$
