Stupid Question... whats the vertex of y=x^2?
Is it 0,0?

Answer 1

yes

Answer 2

whats the vertex of -2(x+3)^2+1
@Data_LG2

Answer 3

y=a(x-h)^2+k
--> (h,k) are the coordinates of the vertex

Answer 4

so 0,3

Answer 5

oh! 3,1

Answer 6

Correct?

Answer 7

which graph would open down? 0,0 or 3,1?

Answer 8

if the value of a is negative then it's open down, if a is positive it's open up

Answer 9

y=x^2 y=-2(x+3)^2+1 which one opens down and which one is more narrow? So the narrow is y=x^2 and opens down is -2(x+3)^2+1

Answer 10

-2(x+3)^2+1 is more narrow

Answer 11

thanks Data

Answer 12

XD lol you already figure it out all by yourself...
