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

Solution

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

Solution

Domain : - \infty < x < \infty

Range : f (x) \leq \frac{21}{4}

X Intercepts : (- \frac{1 + 21}{4}, 0), (\frac{21 - 1}{4}, 0), Y Intercepts : (0, 5)

Vertex : Maximum (- \frac{1}{4}, \frac{21}{4})

Inverse : - \frac{1 + - 4 x + 21}{4}, - \frac{1 - - 4 x + 21}{4}
