extreme y=-4x^2-5x+1

Solution

extreme points

y = - 4 x^{2} - 5 x + 1

Solution

Maximum (- \frac{5}{8}, \frac{41}{16})

Solution steps

f^{'} (x) = - 8 x - 5

Find intervals:

Increasing

: - \infty < x < - \frac{5}{8},

Decreasing

: - \frac{5}{8} < x < \infty

Plug

x = - \frac{5}{8}

into

- 4 x^{2} - 5 x + 1 : \frac{41}{16}

Maximum (- \frac{5}{8}, \frac{41}{16})

Popular Examples

extreme f(x)=|(x^2-7x-6)/(x-5)|extreme points

f (x) = \frac{x ^{2} - 7 x - 6}{x - 5}

extreme (x+1)^3(x-3)extreme points

(x + 1)^{3} (x - 3)

extreme f(x)=2x^3+9x^2-60x+6,-5<= x<= 5 extreme points

f (x) = 2 x^{3} + 9 x^{2} - 60 x + 6, - 5 \leq x \leq 5

extreme f(x)=x^{1/7}extreme points

f (x) = x^{\frac{1}{7}}
