Question 9 of 10

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

what is f(a + 2)?

A. 3+ f(a+2) over f(a)-1

B. (5+ a) over (a-1)

c. (3+a) +2
(a-3)

Answer 1

`\huge\boxed{\sf f(a+2)=(5+a)/(a-1)}`

Explanation:

Given function:

`\displaystyle f(x)=(3+x)/(x-3)`

Put x = a + 2

`\displaystyle f(a+2)=(3+a+2)/(a+2-3) \\\\f(a+2)=(5+a)/(a-1) \\\\\rule[225]{225}{2}`
