Answer:

The value of f(2) is 25.

Step-by-step explanation:

Given,

[tex]f(x) = a^x[/tex]

[tex]\implies f(3) = a^3[/tex]

According to the question,

[tex]f(3)=125[/tex]

[tex]\implies a^3=125\implies a = (125)^\frac{1}{3}=5[/tex]

Hence the function would be,

[tex]f(x) = 5^x[/tex]

If x = 2,

[tex]f(2)=5^2\implies f(2)=25[/tex]
