Guys its my birthday and ill be thankful if someone would help < 3

Answer 1

✔️ all real numbers

Answer 2

Domain is the set of all x values

• To find the range of the set we will put each value as x and record the results in a set I.e. range which is set of y values..

$\large\purple{\sf{f(x)=-2}}$

$\begin{gathered}\\ \sf\longmapsto f(x)=2^{x}-1\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto f(x)=2^{-2}-1\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto f(x)=\frac{1}{2^{2}}-1\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto f(x)=\frac{1}{4}-1\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto f(x)=-\frac{3}{4}\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto ⚘=-0.75\end{gathered}$

$\large\pink{\sf{f(x)=0}}$

$\begin{gathered}\\ \sf\longmapsto f(x)=2^{0}-+\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto f(x)=0-1\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto ⚘=0\end{gathered}$

$\large\blue{\sf{f(x)=3}}$

$\begin{gathered}\\ \sf\longmapsto f(x)=2^{3}-1\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto f(x)=8-1\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto ⚘=7\end{gathered}$

Hence, The set of y values or range of the function is {-0.75,0,7}
