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

monotone intervals

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

Decreasing : - \infty < x < 2, Increasing : 2 < x < \infty

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < 2,

Increasing

: 2 < x < \infty

Decreasing : - \infty < x < 2, Increasing : 2 < x < \infty

g (x) = x + 3

x^{2} - 7

f (x) = \frac{( x + 7 ) ( x - 9 )}{( x - 3 ) ( x + 7 )}

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

y = (x - 4)^{2}
