Question

y=x^2+5x+6 is the vertex -5/2 what is the ordered pair ?

Answer 1

-b/2a that finds and the x coordinate

-5/2(1) = -5/2

we know x=-2.5 we need y to get the second half of the ordered pair
plug in x
y=(-2.5)^2 + 5(-2.5) +6
y= .25
so ( vertex ordered pair is
(-5/2, 1/4)

Answer 2

so the vertex is -5/2 and the ordered pair is 1/4?

Answer 3

you only found the x of the x,y pair
the vertex is an xy pair
-b/2a finds the x and what they call the axis of symmetry

Answer 4

to get the ordered pair plug in the x into the equation.

if youlet x be 0 you will get the y intercept
letting y be 0 you will get the x intercpt
the graph is a parabola
also it points upward becasue a is positive

hope that helps,

Answer 5

that helps a little, thank you
