Popular Examples

f (x) = (\frac{3}{2})^{x} + 4

f(x)=2+3log_{2}(x+1)-log_{4}(2x-1)

f (x) = 2 + 3 lo g_{2} (x + 1) - lo g_{4} (2 x - 1)

f(n)=(log_{10}(n))^2

f (n) = (lo g_{10} (n))^{2}

f(x)=cos(3x)cos(2x)

f (x) = cos (3 x) cos (2 x)

f(x)=(2x^2+7x+3)/(sqrt(x^2+2x-8))

f (x) = \frac{2 x ^{2} + 7 x + 3}{x ^{2} + 2 x - 8}
