Question

Find the interval in which the function f given by f(x)=2x² – 3x is strictly
increasing​

Answer 1

Answer:

$therefore \: the \: function \: is \: strictly \: decreasing.$

Step-by-step explanation:

$\frac{d(f(x))}{dx} = 4x - 3 = 0 \\ \\ x = \frac{3}{4} \\ \\ \frac{ {d}^{2} (f(x))}{d {x}^{2} } = 4 > 0 \\ \\ therefore \: the \: function \: is \: strictly \: decreasing.$
