domain of f(x)=5+2x

domain

f (x) = 5 + 2 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

\frac{x - 7}{x ^{2} + 14 x + 49}

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

f (x) = \frac{4 x + 3}{2 x + 2}

f (x) = 2 x^{2} - x - 6

f (x) = \frac{x ^{2} + 1}{x ^{2} - 3 x + 4}
