A
Given a quadratic in standard form : y = ax² + bx + c ( a ≠ 0 ), then
The x-coordinate of the vertex is
= - 
y = - 3x² + 2x - 7 is in standard form
with a = - 3, b = 2 and c = - 7, hence
= - 
= 
Substitute this value into the equation for y-coordinate
y = - 3 ()² + 2 ( ) - 7
= - + 
- 
= - 
vertex = ( , - ) → A
Answer:
What is y?
Step-by-step explanation:
Answer:
270 degrees
Step-by-step explanation:
If you want a positive number, you can say that the origin is 360 degrees. Then, being it's moving clockwise, subtract 90 degrees from 360 degrees. That will give you 270 degrees.
If you want a negative answer, you could simply say that the origin is 0 and subtract 90 from that giving you -90.
Odds are you should go with 270.
The function ...
... g = |x| + 1
will map any integer x into the set of positive integers g.
