Question 304414: Can u please show me the table and graph of the parabola for this equation. I don't understand how to find the axis of symmetry and how to pick the points on my graph if the vertix isnt a whole number..... here is the problem... y < 4X^2-2X+1 Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Can u please show me the table and graph of the parabola for this equation. I don't understand how to find the axis of symmetry and how to pick the points on my graph if the vertix isnt a whole number..... here is the problem...
y < 4X^2-2X+1
-------------------------
Graph the boundary line, y = 4x^2-2x+1, of the inequality.
---
The axis of symmetry is x = -b/2a = 2/(2*4) = 1/4
-----------------------------------------------------
Pick a couple of x-values to the left and to the right of x = 1/4
---
If x = -2, y = 4(-2)^2-2(-2)+1 = 21
---
If x = -1, y = 4(-1)^2 -2(-1) + 1 = 7
---
If x = 0, y = 1
---
If x = 2 y = 4(2)^2-2(2)+1 = 13
------------------------------------------
Plot the points and draw a smooth curve thru them.
