domain of-(2a-5)/(5+2a)

domain

- \frac{2 a - 5}{5 + 2 a}

a < - \frac{5}{2} or a > - \frac{5}{2}

Interval Notation

(- \infty, - \frac{5}{2}) \cup (- \frac{5}{2}, \infty)

Solution steps

Find undefined (singularity) points:

a = - \frac{5}{2}

The function domain

a < - \frac{5}{2} or a > - \frac{5}{2}

f (x) = arcsin (3 x)

x^{2} e^{- x}

f (x) = lo g_{x} (36 - x^{2})

2 x + 4

2 x + 5
