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

Solution

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

Solution

Domain : - \infty < x < \infty

Range : f (x) \geq \frac{55}{8}

Y Intercepts : (0, 8)

Vertex : Minimum (\frac{3}{4}, \frac{55}{8})

Inverse : \frac{3 + 8 x - 55}{4}, \frac{3 - 8 x - 55}{4}

+1

Popular Examples

y = 7 (x + a)

f(x)=6x^4+7x^3-4

f (x) = 6 x^{4} + 7 x^{3} - 4

f (x) = 1 + 2 x + 3 x^{2}

y=(16x+1)/(x^{-2)}

y = \frac{16 x + 1}{x ^{- 2}}

f(x)= 3/((x^2))

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