Question

Please answer!!!!!!!!!!!

Answer 1

C.
`f(a + 2) = (5 + a)/(a - 1)`

Explanation:

Replace x with a + 2 and simplify the expression.

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

Let x = a + 2

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

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

Answer 2

For this case we have a function of the form
`y = f (x).` Where:

`f (x)=\frac {3 + x}{x-3}`

We must find the value of the function when
`x = a + 2`

So, substituting the value of "x" we have:

`f (a + 2) = \frac {3+ (a + 2)} {(a + 2) -3}`

`f (a + 2) = \frac {3 + a + 2} {a + 2-3}`

`f (a + 2)=\frac {5 + a} {a-1}\\`

Answer:

`f(a + 2) =\frac {5 + a} {a-1}`
