Question 743458
Where is y in your expression?

In any case, to find x-intercept, let y = 0 and solve for x.
To find y-intercepts, let x = 0 and solve for y.
To find domain, set denominator to zero and solve for x.

x+3 = 0

x = -3

The domain is all real numbers except for x = -3.

You can find the intercepts given the above information.
