Hi Jayda..

Your Question: If f(x) = 2 (5)^x, what is f(2)?

Given f(x) = 2 × 5^x

Find f(2)

The question is asking you to find the value of the function f(x) when x =2

So. Substitute the value 2 in for x and solve

f(2) = 2 × 5²

f(2) = 2 × 25

f(2) = 50

So your answer is 50

Hope this helps :)
