Rewrite the function by completing the square.
f(x) = [x² - 2x] - 6
= [(x-1)² - 1] - 6
= (x-1)² - 7
In vertex form,
f(x) = (x-1)² - 7
The vertex is located at (1, -7).
Because the leading coefficient is +1, the curve opens upward.
f(x) = (x - 1)² - 7
based on context clues you gave i'm assuming the answer would be c.
answer: its c because when it has a magnet next to it it will move away from the mixture. hope this
