So to find the x vertex u have to apply the formula x= -b/2a so it will be
x= -(-4)/2(1)
x= 4/2
x= 2
and to find the y vertex u just substitute the x value into the original equation so it will be
y= (2)^2-4(2)+1
y= 4-8+1
y= -3
so the coordinates of the vertex are (2,-3)
Answer:
2 is 13
4 is 1
6 is 16
Step-by-step explanation:
If you were to solve for y, it would be 2. Therefore 2y would be 4.
