Popular Examples

y = \frac{1}{x + 3} + 4

f(x)=x^2-1+2x^3

f (x) = x^{2} - 1 + 2 x^{3}

f(x)=(x+1)^{2/3}(x-2)^{1/3}

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

f(x)=-0.23x^3+4.88x^2-29.77x+133.65

f (x) = - 0.23 x^{3} + 4.88 x^{2} - 29.77 x + 133.65

f(x)=(x-4)/(2x+1)

f (x) = \frac{x - 4}{2 x + 1}
