Given,

The function is,


f(x)=3^x-2_{}

Taking, x = 3 then,

Substituting the value of x in the above expression then,


\begin{gathered} f(x)=3^x-2_{} \\ f(3)=3^3-2 \\ f(3)=9^{}-2 \\ f(3)=7 \end{gathered}

Hence, 7 is the equivalent value of f(3) for the given function.

Therefore, option 1 is correct.
