Question

Please help me ;-; Evaluate the following exponentials at the given values

Given f(x)=5^x-3, find f(5)

Answer 1

Putting x=5 in
`f(x)=\{5^x\}-3` we get f(5)=3122

Explanation:

We need to evaluate
`f(x)=\{5^x\}-3` when f(5)

Finding f(5) we need to put x=5

`f(x)=\{5^x\}-3\\x=5\\f(5)=\{5^5\}-3\\f(5)=3125-3\\f(5)=3122`

So, f(5)=3122

Putting x=5 in
`f(x)=\{5^x\}-3` we get f(5)=3122
