Question

The function 2x2=12x+y-22 has a critical point where x = ____ and y = ____

Help!?

Answer 1

2x² =  12x + y -22

y = 2x² -12x + 22...THAT'S the function

Critical point is where derivative equals zero.

y' = 4x - 12

x=3  so y = 2(9) -36 + 22 ...you can finish the job.

 

CHECK THE WORK (beware of tutor typos) and if necessary fix it...certainly this gives you the method and I hope also the Understanding.
