domain of f(x)=(3a)/(2a+25)

domain

f (x) = \frac{3 a}{2 a + 25}

a < - \frac{25}{2} or a > - \frac{25}{2}

Interval Notation

(- \infty, - \frac{25}{2}) \cup (- \frac{25}{2}, \infty)

Solution steps

Find undefined (singularity) points:

a = - \frac{25}{2}

The function domain

a < - \frac{25}{2} or a > - \frac{25}{2}

f (x) = \frac{x ^{2} - 64}{2 x ^{2} + 10}

f (x) = \frac{6 x + 36}{x}

f (x) = \frac{x}{1 + x}

f (x) = cos (2 x)

y = - 7 x + 2

What is the domain of f(x)=(3a)/(2a+25) ?
The domain of f(x)=(3a)/(2a+25) is a<-25/2 \lor a>-25/2
