domain of (-3x^2-12x-9)/(x^2+5x+4)

domain

\frac{- 3 x ^{2} - 12 x - 9}{x ^{2} + 5 x + 4}

x < - 4 or - 4 < x < - 1 or x > - 1

Solution steps

Find undefined (singularity) points:

x = - 1, x = - 4

The function domain

x < - 4 or - 4 < x < - 1 or x > - 1

49 - x^{2}

f (x) = 80 - 4.9 t^{2}

\frac{4 x ^{2} + 1}{2 x ^{2} + 5 x - 3}

y = 4 cos (π x + \frac{π}{2})

\frac{x + 2}{x}
