domain of (2x^2)/(x^2)+(7x)/(10x)+15/7

domain

\frac{2 x ^{2}}{x ^{2}} + \frac{7 x}{10 x} + \frac{15}{7}

x < 0 or x > 0

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

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

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

f (x) = ln (- 4 + 4)

f (x) = 3 ∣ x ∣ - 4

\frac{- 2 x ^{2}}{( x - 1 ) ( x + 7 )}

What is the domain of (2x^2)/(x^2)+(7x)/(10x)+15/7 ?
The domain of (2x^2)/(x^2)+(7x)/(10x)+15/7 is x<0\lor x>0
