Please help !!! I know nothing about limits

Answer 1

Answer A in your list

Explanation:

Simply replace x in the expression for f(x) with "x+h" and perform any squaring of binomials as needed:

If
`f(x) = (x^2)/(x+3)`, then:

`f(x+h)= ((x+h)^2)/((x+h)+3) =(x^2+2xh+h^2)/(x+h+3)`

which is the first answer in your list of possible options
