The y-intercepts of a rational function are:

• the value of f(0)
• the real zeros of the numerator
• always zero
• the real zeros of the denominatior

Name any holes of the function.

• none
• x=3
• x=-3

Solve and check for extraneous solutions.

• x=-1, x=-3 extraneous
• x=-1 extraneous, x=-2
• x=-1, x=-2 extraneous
• x=-1, x=2 extraneous
