Vertex form

form looks like?
can we determine direction? if so, how?
can we find the y-intercept from this form? if so, how?
can we find coordinate point for the vertex? if so, how?
can we identify the axis of symmetry from this form? if so, how?
can we find the x-intercepts from this form? if so, how?
any other notes to add?
convert this equation into vertex form: y = x2 + 6x + 8
convert this equations into vertex form: f(x) = x2 + 4x - 16

i do not know this sorry : (

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
