Given,
The function is,
[tex]f(x)=3^x-2_{}[/tex]Taking, x = 3 then,
Substituting the value of x in the above expression then,
[tex]\begin{gathered} f(x)=3^x-2_{} \\ f(3)=3^3-2 \\ f(3)=9^{}-2 \\ f(3)=7 \end{gathered}[/tex]Hence, 7 is the equivalent value of f(3) for the given function.
Therefore, option 1 is correct.
