Starting with the graph of f(x)=9x\displaystyle {f{{\left({x}\right)}}}={9}^{{{x}}}, write the equation of the graph that results from

(a) shifting f(x)\displaystyle {f{{\left({x}\right)}}} 2 units upward. y=\displaystyle {y}=  

(b) shifting f(x)\displaystyle {f{{\left({x}\right)}}} 3 units to the left. y=\displaystyle {y}=  

(c) reflecting f(x)\displaystyle {f{{\left({x}\right)}}} about the y-axis. y=\displaystyle {y}=
