Question

For the expression:
(9x^2 + 4y^2 -12xy) / (4y^2 - 9x^2)

Find the domain

Answer 1

Interval Notation (-∞, ∞)

Set-Builder Notation: x ∈ R (all real numbers = R)

Explanation:

I plugged this into a graphing calculator and was able to find the domains by looking at where the lines stopped (they didn't stop) and wrote the f(x) based off of it
