Question

If f(x)= a* and f(3) = 125, find f(2). Assume a > 0. f(2)=0

Answer 1

Answer:

The value of f(2) is 25.

Step-by-step explanation:

Consider the provided function.

$f(x)=a^x$

Where a > 0

It is given that $f(3) = 125$.

If we substitute x=3 in the provided function we get,

$a^3=125$

$a^3=5^3$

Thus the value of a is 5.

The required function is $f(x)=5^x$.

Now solve the function for f(2).

$f(2)=5^2$

$f(2)=25$

Hence, the value of f(2) is 25.
