Question

Let f(x) = 1/x and g(x) = x² – 5x. What

two numbers are not in the domain of fºg?
Separate your answers with a comma.
Enter the correct answer.

Answer 1

5,0

Explanation:

f o g is a composite function, y values of g passed as x values into f.

f o g = 1/(x^2 - 5x)

in this case, the only way for the function to be undefined is when

x^2 -5x = 0

x(x - 5) = 0

x = 0 or x = 5
