Popular Examples

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

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

f(x)=-0.2x^3+3x^2+10x-6

f (x) = - 0.2 x^{3} + 3 x^{2} + 10 x - 6

f(x)=(x+6)/(x^2+9)

f (x) = \frac{x + 6}{x ^{2} + 9}

f(x)=(101)/(4+40e^{-0.25x)}

f (x) = \frac{101}{4 + 40 e ^{- 0.25 x}}

y=((x+1)/(x-1))^2

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