Question

What is the domain of y equals -1/4x squared +1/2x minus 13/4?

Answer 1

If your equation is $y=- \frac{1}{4} x^{2} + \frac{1}{2} x- \frac{13}{4}$, then the domain is all real numbers (-∞, ∞).

If your equation is $y = - \frac{1}{4 x^{2} } + \frac{1}{2x} - \frac{13}{4}$,
then the domain is all real numbers except zero (-∞, 0)∪(0, ∞)
