Question
Suppose that $f(x)$ has domain $[4,8]$ and range $[2,6] .$ Find the domain and range of:$$\begin{array}{ll}{\text { (a) } f(x)+3} & {\text { (b) } f(x+3)} \\ {\text { (c) } f(3 x)} & {\text { (d) } 3 f(x)}\end{array}$$
Step 1
This means that the domain remains the same, but the range is increased by 3. Therefore, the domain is $[4,8]$ and the range is $[2+3,6+3]=[5,9]$. Show more…

Let $y=f(x)$ be a function with domain $D=[-2,6]$ and range $R=[-4,8] .$ Find the domain $D$ and range $R$ for each function. Assume $f(2)=8$ and $f(6)=-4$ (a) $y=-2 f(x)$ (b) $y=f\left(\frac{1}{2} x\right)$ (c) $y=f(x-3)+1$ (d) $y=f(x+2)-3$ (e) $y=f(-x)$ (f) $y=-f(x)$ (g) $y=f(|x|)$ (b) $y=|f(x)|$
