domain of f(x)=x^2+8x+7

domain

f (x) = x^{2} + 8 x + 7

- \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^{2} - 4 x + 4

f (x) = x^{2} + 2 x + 3

\frac{1 - 3 x}{x - 1}

f (x) = lo g_{3} (4 x - 5)

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