1. The problem states: Given the function $$f(x) = \frac{e^x}{x^2}$$, find $$f(x)$$. 2. The function is already given explicitly as $$f(x) = \frac{e^x}{x^2}$$.

1. The problem is to expand the expression $ (x-2)^2 $. 2. Recall that $ (a-b)^2 = a^2 - 2ab + b^2 $.

1. The problem asks us to graph the inverse function $f^{-1}$ given the graph of $f$. 2. The graph of $f$ is a line segment from approximately $(4, -4)$ to $(6, 7)$.

1. The problem is to find the greatest common divisor (GCD) of $a^n$ and $b^n$. 2. Recall the property of GCD for powers: $$\gcd(a^n,b^n) = (\gcd(a,b))^n$$
