Popular Examples

f(x)= 8/5-0<= x<= 3,[ 1/3-2/5 ]

f (x) = \frac{8}{5} - 0 \leq x \leq 3, [\frac{1}{3} - \frac{2}{5}]

f(x)=xsin(x)-cos(x/3)

f (x) = x sin (x) - cos (\frac{x}{3})

f(x)=x^2-1,-3<= x<= 3

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

f(x)=x^2+20x+900

f (x) = x^{2} + 20 x + 900

f (x) = x^{16} + 1
