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

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

x^{2} - 18 x + 82

f (x) = \frac{x ^{3} + 2 x ^{2} - 15 x}{18 x - 2 x ^{3}}

y = 2 x - 3

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

What is the domain of f(x)=x^2-8x-7 ?
The domain of f(x)=x^2-8x-7 is -infinity <x<infinity
