monotone f(x)=-4x^2+6x+1

monotone intervals

f (x) = - 4 x^{2} + 6 x + 1

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

Solution steps

f^{'} (x) = - 8 x + 6

Find intervals:

Increasing

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

Decreasing

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

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