domain of y=5-3x

domain

y = 5 - 3 x

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

f (x) = \frac{x}{x ^{2} + 2 x - 8}

f (x) = \frac{20 - 4 x}{2}

y = \frac{2 x + 14}{x ^{2} - 49}

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

f (x) = \frac{x + 6}{x ^{2} - 4}
