What is the first step in writing f(x) = 3x2 + 6x – 8 in vertex form?
kkurt [141]
The first step in writing f(x) = 3x² + 6x - 8 in vertex form is

E. Factor out 3 from the first two terms.

f(x) = 3x² + 6x - 8
f(x) = 3(x² + 2x) - 8
f(x) + 8 = 3(x² + 2x + __)
f(x) + 8 + 1 = 3(x² + 2x + 1)
f(x) + 9 = 3(x+1)²
f(x) = 3(x+1)² - 9

Can someone help me correct number 6 please and thank you! Please Explain and Show Your Work!
NNADVOKAT [17]

Answer:

You have your x and y mixed up

Step-by-step explanation:

Look at your table.  You labeled y1 and y2 where the x's are.  y2 = 8, y1 = 4, x2 = 12 and x1 = 6.  The slope then is (8-4)/(12-6) which is 4/6 or 2/3.  You did run over rise instead of rise over run.  Be careful.  I see that a lot when I teach the concept to beginners.

To reflect a point over the x-axis, simply make its x-value negative. So, we can take the sample point of (1,1), make its x-value negative, and get (-1,1).
