monotone f(x)=2x^2+3x-4

monotone intervals

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

Decreasing : - \infty < x < - \frac{3}{4}, Increasing : - \frac{3}{4} < x < \infty

Solution steps

f^{'} (x) = 4 x + 3

Find intervals:

Decreasing

: - \infty < x < - \frac{3}{4},

Increasing

: - \frac{3}{4} < x < \infty

Decreasing : - \infty < x < - \frac{3}{4}, Increasing : - \frac{3}{4} < x < \infty

(3, - 1), (- 5, 2)

\frac{1}{1 - x}

- x - 3

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

\frac{1}{6 - x}

What is the monotone f(x)=2x^2+3x-4 ?
The monotone f(x)=2x^2+3x-4 is Decreasing:-infinity <x<-3/4 ,Increasing:-3/4 <x<infinity
