Answer & Solution

Correct Answer

(B) 23

Step-by-step Solution

Detailed explanation

Given, fx=6x2-18x+216x2-18x+17 ⇒fx=1+46x2-18x+17 Now let gx=6x2-18x+17 Now we will find minimum value of gx by differentiating it we get, g'x=12x-18 ⇒g'x=0⇒12x-18=0 ⇒x=32 Now putting the value of x in gx we get, g32=72 Now putting the minimum value of gx…
