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

Solution

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

Solution

Domain : - \infty < x < \infty

Range : f (x) \geq - \frac{9}{4}

X Intercepts : (1, 0), (- 2, 0), Y Intercepts : (0, - 2)

Vertex : Minimum (- \frac{1}{2}, - \frac{9}{4})

Inverse : \frac{- 1 + 4 x + 9}{2}, \frac{- 1 - 4 x + 9}{2}

f(x)=x^4-2x^3-3x^2

f (x) = x^{4} - 2 x^{3} - 3 x^{2}

f(x)=12cosh(6x)sinh(6x)+6sinh(12x)

f (x) = 12 cosh (6 x) sinh (6 x) + 6 sinh (12 x)

f(x)=\sqrt[4]{3x-21}

f(x)= 1/x ,1<= x<= 3

f (x) = \frac{1}{x}, 1 \leq x \leq 3
