Evaluate the function rule for the given value. f(x) = 15^x for x = 3

Solution:

A function is a process or a relation that associates each element 'a' of a non-empty set A , at least to a single element 'b' of another non-empty set B.

A relation f from a set A (the domain of the function) to another set B (the co-domain of the function) is called a function in math.

f = {(a,b)| for all a ∈ A, b ∈ B}

It is given that

f(x) = 15^x for x = 3

When x = 3

f(3) = 15³

f(3) = 15 × 15 × 15

f(3) = 3375

Therefore, evaluating the function rule for the given value we get 3375.

Evaluate the function rule for the given value. f(x) = 15^x for x = 3

Summary:

Evaluating the function rule for the given value f(x) = 15^x for x = 3 we get 3375.
