g(x)=2x^2-6x-56

Solution

g (x) = 2 x^{2} - 6 x - 56

Solution

Domain : - \infty < x < \infty

Range : f (x) \geq - \frac{121}{2}

X Intercepts : (7, 0), (- 4, 0), Y Intercepts : (0, - 56)

Vertex : Minimum (\frac{3}{2}, - \frac{121}{2})

Inverse : \frac{3 + 2 x + 121}{2}, \frac{3 - 2 x + 121}{2}

+1

Popular Examples

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

f(x)= 3/4 x^4-8x^2

f (x) = \frac{3}{4} x^{4} - 8 x^{2}

f(x)=sqrt(x+1)+sqrt(x)

f (x) = x + 1 + x

f (x) = 25 x^{2} - 81

y = x^{3} x^{5}
