Question

Given the function defined by g(x)=x²+4x-3, find g (s).

Answer 1

`g(s)=s^(2) +4s-3`

Explanation:

• If we have a function f(x) and want to find f(a) , just substitute by x=a in the Equation of f(x) , the Result will be f(a)

So for our Question , we have
`g(x)=x^(2) +4x-3`

and we want to find g(s) , so just substitute by x = s in the Equation of g(x)

`g(s)=s^(2) +4s-3`
