Answer:
C
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
Given
y = 2x² + 12x + 1
To express in vertex form use the method of completing the square.
The coefficient of the x² term must be 1 , thus factor out 2 from 2x² + 12x
y = 2(x² + 6x) + 1
add/ subtract ( half the coefficient of the x- term)² to x² + 6x
y = 2(x² + 2(3)x + 9 - 9) + 1
= 2(x + 3)² - 18 + 1
= 2(x + 3)² - 17 → C
Answer:
answer : C 2(x-3)²-17
Step-by-step explanation:
hello :
answer : C 2(x-3)²-17
calculate : 2(x-3)²-17 = 2(x²-6x+9)-17 = 2x²-12x+18-17
2(x-3)²-17 = 2x²-12x+1.....(right)
