Find (fog)(x) when f(x)=x^2 + 6x + 5 and g(x)= 1/x+1

For this case we have the following functions:

We must find By definition of composition of functions we have to:

So, we have:

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
