Question

12. PLEASE HELP ME

Which of the following are the coordinates of the vertex of y= x2 - 10x + 2?

A. (–10, 2)

B. (2, –10)

C. (–5, 23)

D. (5, –23)

Answer 1

D. (5, –23)

Explanation:

The vertex is in essence the turning point of the parabola y = x² − 10x + 2

the x coordinate of the turning point =

=

= 5

when x = 5, y = (5)² - 10(5) + 2

= -23

Thus coordinate or vertex is ( 5, -23)

5 right 23 down

Answer 2

I think b no. is the correct answer
