Answer:
Answer A in your list
Step-by-step explanation:
Simply replace x in the expression for f(x) with "x+h" and perform any squaring of binomials as needed:
If [tex]f(x) = \frac{x^2}{x+3}[/tex], then:
[tex]f(x+h)= \frac{(x+h)^2}{(x+h)+3} =\frac{x^2+2xh+h^2}{x+h+3}[/tex]
which is the first answer in your list of possible options
