Write the function f(x) = 3x2 - 6x + 5 in vertex
weeeeeb [17]
3(x-1)^2 +2
This is your answer in vertex form, your h and k values are the vertex. Solving the function by using b/2a, we get that h is 1. ( in the equation 3 is your a, 6 is b and 5 is c.). ( 6/2(3)) = 1. We can then plug in 1 as x into the original equation and get positive 2 ( 3(1)^2 -6(1) +5) = 3-6+5 = 2. This is your vertex. In the function, your a value will always stay the same as this is your shrink or stretch. In this case, a is 3 so it will go outside the parenthesis. Put that all together and you get the function above.
Hope this helps :)

In their last game, the school football team scored an equal number of points in each of the first three quarters, then 14points
Ksenya-84 [330]

Answer:

10 points

Step-by-step explanation:

Points scored in each of the first 3 quarter = x

Total points scored in the first 3 quarter = x + x + x

= 3x

Points scored in the fourth quarter = 14

Total points scored = 44 point

Total points scored = Total points scored in the first 3 quarter + Points scored in the fourth quarter

44 = 3x + 14

Subtract 14 from both sides

44 = 3x + 14

44 - 14 = 3x + 14 - 14

30 = 3x

Divide both sides by 3

x = 30/3

= 10

x = 10 points

Points scored in each of the first 3 quarter = x = 10 points

The school football team scored 10 points points in the first quarter
