Solve by graphing.

Graphing help: Double-click the green $\displaystyle {f{{\left({x}\right)}}}={x}^{{2}}$ to change $\displaystyle {f{{\left({x}\right)}}}$. Single-click the box below the green $\displaystyle {f{{\left({x}\right)}}}$ to add another function. No need to include function notation when entering a function. Just enter the formula, as in $\displaystyle {2}^{{x}}-{3}$.

$\displaystyle {2}^{{x}}={\left({x}+{3}\right)}^{{2}}-{1}$



$\displaystyle {x}=$
