f(x)=$x^{2}$ $3^{x}$ $-3^{x+2}$
You asked:
Evaluate the function \(f\left( x \right) = {x}^{2}\), \({3}^{x} - {3}^{x + 2}\).
MathBot Answer:
$$\begin{aligned}{3}^{x} - {3}^{x + 2}&=- 8 \cdot 3^{x}\end{aligned}$$
$$\begin{aligned}{3}^{x} - {3}^{x + 2}&=3^{x} - 3^{x + 2}\\{3}^{x} - {3}^{x + 2}&=3^{x} - 9 \cdot 3^{x}\\{3}^{x} - {3}^{x + 2}&=3^{x} + - 9 \cdot 3^{x}\\{3}^{x} - {3}^{x + 2}&=- 8 \cdot 3^{x}\\\end{aligned}$$
