Question

Hich of the following are the coordinates of the vertex of y = x2 − 10x + 2?

Answer 1

5 right 23 down

Explanation:

i got 100%

Answer 2

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

the x coordinate of the turning point =
`- (b)/(2a)`
=
`- (-(10))/(2(1))`
= 5

when x = 5, y = (5)² - 10(5) + 2
= -23

Thus coordinate or vertex is ( 5, -23)
