domain of y=(x^2)/(4-x)

domain

y = \frac{x ^{2}}{4 - x}

x < 4 or x > 4

Interval Notation

(- \infty, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = 4

The function domain

x < 4 or x > 4

f (t) = t + 3

f (x) = \frac{23 x + 24}{x}

f (x) = - 3 + lo g_{2} (x - 2)

f (x) = - \frac{1}{( x - 2 ) ^{2}}

f (x) = \frac{x ^{2} - 10 x - 56}{2 x ^{2} + 8 x}

What is the domain of y=(x^2)/(4-x) ?
The domain of y=(x^2)/(4-x) is x<4\lor x>4
