domain of f(x)=(4-s^2)/(2s^2-7s-4)

domain

f (x) = \frac{4 - s ^{2}}{2 s ^{2} - 7 s - 4}

s < - \frac{1}{2} or - \frac{1}{2} < s < 4 or s > 4

Interval Notation

(- \infty, - \frac{1}{2}) \cup (- \frac{1}{2}, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

s = 4, s = - \frac{1}{2}

The function domain

s < - \frac{1}{2} or - \frac{1}{2} < s < 4 or s > 4

\frac{2 x - 4}{x + 4}

\frac{7 x}{x ^{2} - 2 x - 8}

f (x) = lo g_{e} (x^{2} - 1)

f (x) = \frac{1}{- x ^{2} + 6 x}

\frac{3 - x + 1}{x + 1 - 1}
