4. (08.07 mc) which graph shows the quadratic function y = 3x2 + 12x + 14? (5 points) the following graph is labeled a: a four quadrant graph with a parabola opening up, passing through the points negative 3, 1, negative 2, negative 2, and negative 1, 1 with the vertex at 2, negative 2. the following graph is labeled b: a four quadrant graph with a parabola opening up, passing through the points 1, 4, 2, 1, and 3, 4 with the vertex at 2, 1. the following graph is labeled c: a four quadrant graph with a parabola opening up, passing through the points negative 3, 5, negative 2, 2, and negative 1, 5 with the vertex at negative 2, 2. the following graph is labeled d: a four quadrant graph with a parabola opening up, passing through the points 1, 1, 2, negative 2, and 3, 1 with the vertex at 2, negative 2. a b c d

C

Step-by-step explanation:

You have a vertex of (-2,2) since -b/(2a)=-12/(2*3)=-12/6=-2

and then plug it in for the y-coordinate 3(-2)^2+12(-2)+14=2

So you have a vertex of (-2,2).

The parabola is open up since 3 is positive.

So far it looks like the choice is C because it is the only one that says the vertex is (-2,2) and it does have that it is open up.

Let' s look at (-3,5) and (-1,5).

So if we plug in -3 into 3x^2+12x+14 we get 3(-3)^2+12(-3)+14=5 check mark

what about x=-1?  3(-1)^2+12(-1)+14=5

Bingo! C checks out!

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings

your pal papaguy

y = -1

x = 8

hope this !
