Solution

f (x) = x^{3} + x^{2} - 9 x - 18

Solution

Domain : - \infty < x < \infty

Range : - \infty < f (x) < \infty

X Intercepts : (3.32854 \dots, 0), Y Intercepts : (0, - 18)

Asymptotes : None

Extreme Points : Maximum (- \frac{1 + 2 7}{3}, \frac{2 - 50 7}{27} + 67 - 15), Minimum (\frac{- 1 + 2 7}{3}, \frac{50 7 + 2}{27} - 67 - 15)

y = 10 - 16 x - 4 x^{2}

f (x) = 6 x^{2} + 4 x - 3

y=cos(3/(4x))-2

y = cos (\frac{3}{4 x}) - 2

y=(x^2+x^3+4x^1)/(2+7)

y = \frac{x ^{2} + x ^{3} + 4 x ^{1}}{2 + 7}

y = ln ((3 x + b)^{2})
