domain of f(x)=(3x)/(4-x)

domain

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

- 6 \cdot \frac{1}{cos ( 5 )} (y + π) + 5

f (x) = 4 - 7 t

f (x) = 2 x^{2} - 3 x + 4

3 x - 10

f (x) = ∣ x - 2 ∣ + 1

What is the domain of f(x)=(3x)/(4-x) ?
The domain of f(x)=(3x)/(4-x) is x<4\lor x>4
