Question

Match each function with the point that represents the vertex of its graph. No one point be used more than once.

Answer 1

so if a function is written in this form: \[y=ax^2+bx+c\] the x coordinate of the vertex is \[-b/2a\] and you can take this x coordinate and plug back into the equation to get the y coordinate

Answer 2

that is if a function is written in standard form ^

Answer 3

if a function is written in vertex form \[y=a(x-h)^2+k\]
(h, k) is the vertex

Answer 4

for your number 2: \[y=-2(x+2)^2\]
there is no k so k = 0
h = -2 here do you get this?

Answer 5

for your number 5:\[y=-2x^2+4x+2\]
find -b/2a, where in this case a= -2 and b = 4,
thats the x coordinate of the vertex then plug in the x coordinate into the function to find the y-coordinate

Answer 6

If you have something in this form \[(x+1)(x+2)\] you can use FOIL and factor this out into
x^2 + 2x + x + 2 = x^2 +3x+2
