domain of f(x)=(x^2)/(3-x)

domain

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

x < 3 or x > 3

Solution steps

Find undefined (singularity) points:

x = 3

The function domain

x < 3 or x > 3

lo g_{10} (4 x - x^{2})

f (x) = \frac{x}{3 x - 6}

f (x) = \frac{( x - 2 ) ( x + 5 )}{x + 2}

\frac{x ^{2} - 100}{x ^{2} + x - 90}

∣ x ∣ - 2

What is the domain of f(x)=(x^2)/(3-x) ?
The domain of f(x)=(x^2)/(3-x) is x<3\lor x>3
