f(x)=2x^2-11x-1

Solution

f (x) = 2 x^{2} - 11 x - 1

Solution

Domain : - \infty < x < \infty

Range : f (x) \geq - \frac{129}{8}

X Intercepts : (\frac{11 + 129}{4}, 0), (\frac{11 - 129}{4}, 0), Y Intercepts : (0, - 1)

Vertex : Minimum (\frac{11}{4}, - \frac{129}{8})

Inverse : \frac{11 + 8 x + 129}{4}, \frac{11 - 8 x + 129}{4}

+1

f(x)=csc(x)+csc(2x)+cot(2x)

f (x) = csc (x) + csc (2 x) + cot (2 x)

f(x)=x^5+2x^4-13x^3-26x^2+36x+72

f (x) = x^{5} + 2 x^{4} - 13 x^{3} - 26 x^{2} + 36 x + 72

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

f(x)=x(-sin(x))

f (x) = x (- sin (x))

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

f (x) = x^{2} (x - 1)^{2}
