monotone f(x)=(-5x+1)^2

monotone intervals

f (x) = (- 5 x + 1)^{2}

Decreasing : - \infty < x < \frac{1}{5}, Increasing : \frac{1}{5} < x < \infty

Solution steps

f^{'} (x) = - 10 (- 5 x + 1)

Find intervals:

Decreasing

: - \infty < x < \frac{1}{5},

Increasing

: \frac{1}{5} < x < \infty

Decreasing : - \infty < x < \frac{1}{5}, Increasing : \frac{1}{5} < x < \infty
