Mathematics

3 0

Answer:

To answer items such as this, we directly substitute the a + 2 to the all the x's in the function such that,

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

Simplifying the function generated above,

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