f(x)=5x^2-2x-8

Solution

f (x) = 5 x^{2} - 2 x - 8

Solution

Domain : - \infty < x < \infty

Range : f (x) \geq - \frac{41}{5}

X Intercepts : (\frac{1 + 41}{5}, 0), (\frac{1 - 41}{5}, 0), Y Intercepts : (0, - 8)

Vertex : Minimum (\frac{1}{5}, - \frac{41}{5})

Inverse : \frac{1 + 5 x + 41}{5}, \frac{1 - 5 x + 41}{5}

+1

Popular Examples

f (x) = 5 x^{2} - 2 x + 2

f(x)=4x^2-12x-9

f (x) = 4 x^{2} - 12 x - 9

f(x)=(5x^2-16x-16)/(2x^2+x-21)

f (x) = \frac{5 x ^{2} - 16 x - 16}{2 x ^{2} + x - 21}

f(x)=x^2e^x+2sin(x)+sqrt(1/5)

f (x) = x^{2} e^{x} + 2 sin (x) + \frac{1}{5}

f(x)=-2sin(5x-pi/2)+3

f (x) = - 2 sin (5 x - \frac{π}{2}) + 3
