Solution

domain

x - 18

Solution

x \geq 18

+1

Interval Notation

[18, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 18

The function domain

x \geq 18

Popular Examples

intercepts of f(x)=(-31(x-1)^2)/(x-5)intercepts

f (x) = \frac{- 31 ( x - 1 ) ^{2}}{x - 5}

range of 2/(x-2)range

\frac{2}{x - 2}

inverse of f(x)= 1/14 x-19 inverse

f (x) = \frac{1}{14} x - 19

extreme f(x)= 9/((x^2+1))extreme points

f (x) = \frac{9}{( x ^{2} + 1 )}

asymptotes of (2x^2-6x+1)/(1+x^2)asymptotes

\frac{2 x ^{2} - 6 x + 1}{1 + x ^{2}}
