Popular Examples

domain of 1/(x^2-x-6)domain

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

domain of f(x)=(x^2)/4 domain

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

domain of f(x)= 1/(sqrt(1.4x-9.3x^2))domain

f (x) = \frac{1}{1.4 x - 9.3 x ^{2}}

domain of f(x)= 1/(4x-1)domain

f (x) = \frac{1}{4 x - 1}

domain of (2x+3)/(x+2)domain

\frac{2 x + 3}{x + 2}
