domain of f(x)=((3x))/(x-7)

domain

f (x) = \frac{( 3 x )}{x - 7}

x < 7 or x > 7

Interval Notation

(- \infty, 7) \cup (7, \infty)

Solution steps

Find undefined (singularity) points:

x = 7

The function domain

x < 7 or x > 7

f (x) = x^{4} + x^{2} - 1

y = \frac{2 + x}{x ^{2}}

f (x) = x + 6 - 7

∣ x ∣ + ∣ x + 1 ∣ + ∣ 3 - x ∣

f (x) = 9995 \cdot 0.8 2^{0}

What is the domain of f(x)=((3x))/(x-7) ?
The domain of f(x)=((3x))/(x-7) is x<7\lor x>7
