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:
-3/8
Step-by-step explanation:
First rewrite -2 2/3 as an improper fraction: -8/3
Now invert this result: -3/8
This is the reciprocal of -2 2/3.
