x \geq \frac{9}{2}

The function domain

x \geq \frac{9}{2}

Popular Examples

domain of f(x)=(x^2-2x)/(x^2-3x+2)domain

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

domain of f(x)=(5x+14)/(6x^2+x-2)domain

f (x) = \frac{5 x + 14}{6 x ^{2} + x - 2}

domain of f(x)=(x+9)/(x^2-49)domain

f (x) = \frac{x + 9}{x ^{2} - 49}

domain of 3/(sqrt(3x+2)-\sqrt{3x-2)}domain

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

domain of f(x)=sqrt(1-(|x+1|)/(|x-1|))domain

f (x) = 1 - \frac{∣ x + 1 ∣}{∣ x - 1 ∣}
