What is f(a+2)? what is the function

(5+a)/(a-1)

Step-by-step explanation:

If f(x) = (3+x)/(x-3)

f(a+2) = ?

You replace x with a + 2

So, f(x) = f(a+2)

f(a+2) = (3+a+2)/(a+2-3)

f(a+2) = (5+a)/(a-1)

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
