domain of y=cos((3x^2)/(x+2))

domain

y = cos (\frac{3 x ^{2}}{x + 2})

x < - 2 or x > - 2

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = - 2

The function domain

x < - 2 or x > - 2

y = (x - 1)

f (x) = 3 x^{2} - 13

f (x) = cos (2 x) - sin (x)

f (x) = sin (x) + sin^{2} (x)

y = x^{(2)} + 8 x + 18

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