f(x)=4x^2+x-8

Solution

f (x) = 4 x^{2} + x - 8

Solution

Domain : - \infty < x < \infty

Range : f (x) \geq - \frac{129}{16}

X Intercepts : (\frac{- 1 + 129}{8}, 0), (\frac{- 1 - 129}{8}, 0), Y Intercepts : (0, - 8)

Vertex : Minimum (- \frac{1}{8}, - \frac{129}{16})

Inverse : \frac{- 1 + 16 x + 129}{8}, \frac{- 1 - 16 x + 129}{8}
