k = 5
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
To obtain this form use the method of completing the square
Since the coefficient of the x² term is 1 then
add/ subtract (half the coefficient of the x-term )² to x² - 6x
f(x) = x² + 2(- 3)x + 9 - 9 + 14 = (x - 3)² + 5 → k = 5
Answer:
B
Step-by-step explanation:
The answer is B, -12.
Please give me brainliest.
-12^2 --> -144
-144+144 = 0
Therefore, the answer is B, -12.
Answer:
3?
Step-by-step explanation:
i think that because it's multiplying by 3.
3*3= 9
5*3= 15
7*3= 21
9*3= 27
This is the only way i could think of helping in some sort of way! I'm sorry if it's wrong! (´。＿。｀)
Have a great day! (´。＿。｀) / (ﾉ◕ヮ◕)ﾉ*:･ﾟ✧

Answer:
y+6=2(x-3)
Step-by-step explanation:
y-y1=m(x-x1)
y-(-6)=2(x-3)
y+6=2(x-3)
