domain of f(x)=x^2-20

domain

f (x) = x^{2} - 20

- \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

ln (\frac{1}{9 - ( x + 2 ) ^{2}})

f (x) = \frac{3}{x - 6}

y = \frac{2 x ^{2} - 5 x + 3}{4 x - 10}

y = 3 2 x + \frac{1}{4}

y = x^{2} - 7 x - 82
