domain of-x^2+x+12

domain

- x^{2} + x + 12

- \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

f (x) = 20 x + 5

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

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

\frac{ln ( x )}{ln ( 3 )}

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