For the expression y + 6 − 3, determine the coefficient for the variable term. a) 0
b) 1
c) 3
d) 6
Correct answer gets brainliest, thanks, and good review.

The coefficient should be C

Step-by-step explanation:

I hope this helped

D

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 vertex and a is a multiplier

here (h, k) = (- 3, - 6), thus

y = a(x + 3)² - 6

To find a substitute (0, 0) into the equation

0 = 9a - 6 ⇒ a = =

y = (x + 3)² - 6 ← in vertex form

Expand (x + 3)² and distribute by

y = (x² + 6x + 9) - 6

  = x² + 4x + 6 - 6

  = x² + 4x  ← in standard form
