1. If , 1-38 HW eTool (Desmos) Homework Help ✎

1. Find the domain and range of f(x).

2. Find expressions for f(−x), , and f(x + h).

Domain: Notice the x in the denominator. What values of x must be excluded?
Range: Notice that x is squared. What does this mean about the outputs of f(x)? Furthermore, what will the +1 do to the range?

$f(\sqrt{x})=\frac{3}{(\sqrt{x})^{2}}+1=\text{\ \ \ \ \ \ \ SIMPLIFY}$
