Answer:
you would be 20
Step-by-step explanation:
easy peasy
You answer would be Oy= 7x-1. I hope this helps!
D
You figure out the absolute value by determining how far the number is from the point 0 on a number line.
I leaerned this neat trick
you don't need to convert to vertex form
where
y=ax^2+bx+c
the x value of the vertex is -b/2a
the y value is found by inserting the x value of the vertex into the equation
so
1x^2-6x+14
-b/2a=-(-6)/2(1)=6/2=3
plug that in
y=x^2-6x+14
y=3^2-6(3)+14
y=9-18+14
y=5
the vertex is (3,5)
