Popular Examples

f(x)=(log_{5}(x))^2

f (x) = (lo g_{5} (x))^{2}

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

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

f(x)=(2arctan(x)-ln(1+x^2))

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

f(x)=4x^2-36x+87

f (x) = 4 x^{2} - 36 x + 87

f(x)=(5x^2-49x+36)/(2x^2-18)

f (x) = \frac{5 x ^{2} - 49 x + 36}{2 x ^{2} - 18}
