f(x)=3x^2-7x-8

Solution

f (x) = 3 x^{2} - 7 x - 8

Solution

Domain : - \infty < x < \infty

Range : f (x) \geq - \frac{145}{12}

X Intercepts : (\frac{7 + 145}{6}, 0), (\frac{7 - 145}{6}, 0), Y Intercepts : (0, - 8)

Vertex : Minimum (\frac{7}{6}, - \frac{145}{12})

Inverse : \frac{7 + 12 x + 145}{6}, \frac{7 - 12 x + 145}{6}

Popular Examples

y=x(175-2x)(100-2x)

y = x (175 - 2 x) (100 - 2 x)

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

f(x)=((x^3+x^2+x+1))/(|x+1|)

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

f(x)=(|x^2-4x-5|)/(x-5)

f (x) = \frac{x ^{2} - 4 x - 5}{x - 5}

f(x)=x^3ln(x)-(x^3)/3

f (x) = x^{3} ln (x) - \frac{x ^{3}}{3}
