Answer:
y = x² - 6x + 7
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the turning point and a is a multiplier
Here (h, k) = (3, - 2 ) and letting a = 1
y = (x - 3)² - 2 ← expand using FOIL
= x² - 6x + 9 - 2 ← collect like terms
= x² - 6x + 7
