To do these, start by looking at the "b" value -6.
divide it by 2
-6/2 = -3
now square this number
(-3)^2 = 9
this is what you need for the "c" value
there is only a 5 for the c value so add 4 to both sides of the equation. ( +4 = +4)
y +4 = x^2 -6x +5 +4
y +4 = x^2 -6x +9
y +4 = (x -3)^2
y = (x -3)^2 - 4
vertex ( 3, -4) upwards facing like a bowl, because the "a" value is positive. So the vertex is the minimum, lowest point on the graph.
104 Because 100*4 = 400 and 4*4 = 16 so add together and get 416
Answer:

Step-by-step explanation:
For the orange table:
<em> </em>Substitute the corresponding values of <em>x</em> into the function
, then:
For a:
x=0

For b:
x=2

For c:
x=4

For the blue table:
<em> </em>Substitute the corresponding values of <em>x</em> into the function
, then:
For d:
x=0

For e:
x=2

For f:
x=4

2x+38=50
2x+38-38=50 -38
2x =12
2x/2 =12/2
x=6
