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

domain

f (s) = \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

y = sin (x) + cos (x)

3 \cdot (\frac{3}{5})^{x + 2} - 4

x - 1 - 1

y = - \frac{4 x - 3}{x - 1}

\frac{x ^{2} - x - 6}{x ^{2} - 4 x + 3}
