domain of f(x)=(4-t^2)/(2-t)

domain

f (x) = \frac{4 - t ^{2}}{2 - t}

t < 2 or t > 2

Interval Notation

(- \infty, 2) \cup (2, \infty)

Solution steps

Find undefined (singularity) points:

t = 2

The function domain

t < 2 or t > 2

f (x) = - \frac{3}{2} x^{2} + 44.5 x

4 x^{2} - 4 x

f (x) = 36 - 12 x

\frac{9 + x}{1 - 9 x}

f (x) = \frac{4 + 7 x}{x - 1}

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