How would you know if the endpoint of the graph of an inequality should be a solid dot or open dot?
If the inequality includes 'or equal' then use a solid dot [the value is included]. If it doesn't use 'or equal' then use the open dot.
Is the dot open or closed if it is less than?
The dot is open, if it is less than or equal to than the dot is closed
In which direction does the parabola?
A parabola can open left, down, right, or left on a graph, if that's what you mean:\
If it is greater than is it a open dot or a closed dot?
Well, honey, if the inequality is strictly greater than, like ">", then it's an open dot because that endpoint ain't included in the solution. But if it's greater than or equal to, like ">=", then you better believe it's a closed dot because that endpoint is part of the party. Hope that clears things up for ya!
How do you graph the absolute value of x is less than or equal to 4?
use a line graph. Place a solid dot at 4. Shade the entire region to the left of 4.x is Less than shade Left.* * * * * The above answer is so very wrong - it has missed out the key word "absolute".Use a line graph. Put a solid dot at -4 and another solid dot at +4 and join them. Every point on the line (including the two end points) is the graph.
