Question

The range of values of x in which
f(x) = x2 - 6x + 3 is increasing, is
(A) [3,00) (B) (-3, 3]
(C) [0, 3] (D) (-0,3]​

Answer 1

Answer:

$f(x) = {x}^{2} - 6x + 3 \\ \\ incresing \: \: in \: \: (3 \: . \: \infty ) \\ \\ \\ option \: \: (a)$

Answer 2

Answer:

x∈[3,∞)

Step-by-step explanation:

For increasing function $\frac{dy}{dx\\}$$\geq 0$

y=$x^{2}$-6x+3

$\frac{dy}{dx}$= 2x-6 $\geq$ 0

x≥ 3
