domain of f(x)=2x^2-9

domain

f (x) = 2 x^{2} - 9

- \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

x - 16 y = 10

(6, 0), (0, 7)

\frac{x ^{2} + 7}{x ^{2} - 5 x - 14}

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

\frac{x ^{2}}{x - 1}
