Directrix (directrix):

If f(x) = 2x - 1 f(-x) = 2* (-x) - 1

Directrix (directrix):

f(-x) = 2* (-x) - 1 f(-x) = -2x - 1 ------------- The task is to graph y = -2x - 1

OpenStudy (shaleiah):

hang on..

Directrix (directrix):

I graphed over at Desmos.com

OpenStudy (shaleiah):

The instructor wants me to print it and graph the grid on paper.

Directrix (directrix):

On the grid paper, put dots on the grid to represent the points of (0,-1) and (2, -5) Two points determine a line so draw the line passing through those two points.

Directrix (directrix):

See attached.

Directrix (directrix):

If you put your graph on this thread, I'll check it for you.

OpenStudy (shaleiah):

alright :)

Directrix (directrix):

Be careful as you count units to locate the two points.

Directrix (directrix):

Once you get the points in the right place, draw the line joining them.

@Directrix

Directrix (directrix):

That looks good.

OpenStudy (shaleiah):

thanks for your help!

Directrix (directrix):

One suggestion. I would write the coordinates of the two points on the graph or in the margin of the grid so that the teacher could see which two points I graphed to get the graph of the line.
