Popular Examples

domain of f(x)=x^4-8x^2+12 domain

f (x) = x^{4} - 8 x^{2} + 12

domain of y=16ln(9x-7)domain

y = 16 ln (9 x - 7)

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

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

domain of f(x)=sqrt(2x+1)+sqrt(2-x)domain

f (x) = 2 x + 1 + 2 - x

domain of f(x)=(2x-7)/(2x)domain

f (x) = \frac{2 x - 7}{2 x}
