f(x)=-3x^2+2x-9

Solution

f (x) = - 3 x^{2} + 2 x - 9

Solution

Domain : - \infty < x < \infty

Range : f (x) \leq - \frac{26}{3}

Y Intercepts : (0, - 9)

Vertex : Maximum (\frac{1}{3}, - \frac{26}{3})

Inverse : - \frac{- 1 + - 3 x - 26}{3}, \frac{- 3 x - 26 + 1}{3}

+1

Popular Examples

f(x)=x+6sqrt(x)+8

f (x) = x + 6 x + 8

f(x)=(x^2+3)/(x^2-9)

f (x) = \frac{x ^{2} + 3}{x ^{2} - 9}

y = 7 - x

y=(x^3+8)/(x^2+5x+6)

y = \frac{x ^{3} + 8}{x ^{2} + 5 x + 6}

y=(1/2)^{x-3}+1

y = (\frac{1}{2})^{x - 3} + 1
