Question

4+xThe function g is defined by g(x) =5 + 3xFind g(5n).

Answer 1

The function g is defined by:

g(x) = (4 + x) / (5 + 3x) ...(1)

Now, we need to find g(5n); that is, we make: x = 5n

Replacing this into equation (1):

g(5n) = (4 + 5n) / (5 + 3*(5n)) = (4 + 5n) / (5 + 15n)

So, the final answer is:

g(5n) = (4 + 5n) / (5 + 15n)
