Question

Determine whether the graph of y = x2 − 4x + 1 has a maximum or minimum point, then find the maximum or minimum value.

Minimum; (2, -3)

Maximum; (2, -3)

Minimum; (-3, 2)

Maximum; (-3, 2)

Answer 1

the x^2 is positive so it will have a minimum value

Answer 2

y = x^2 − 4x + 1
= (x - 2)^2 -4 + 1
= (x-2)^2 - 3

- so minimum is at (2, -3)

Answer 3

2nd option

Answer 4

Wouldn't it be the first one? because its min not max? @cwrw238

Answer 5

oh sorry - yes you are right
