Question 946075: What is a sign graph and when is it used? Give an example. Explain what the test-point method is and how it is used to solve a quadratic inequality. Be sure to show the connection between the test-point method and a sign graph. (I am completely lost Please Help!) Answer by rothauserc (4718) (Show Source):

: Sovle each inequality by making a sign graph of the factors. State the solution set in iterval notation and graph it? 5x-x^2<4

Question 982479: Can someone please help me with my homework? Thanks :D 1.What if I have +√3 and -√3 as the roots. What is the equation? 2. Graph the equation in a sign graph: x^2+8x-7=0 In question no. 2, I find the roots of it first. Since it's not a perfect square trinomial, and 8 is an even number, I used completing the square. x^2+8x=7 …

Start with one of your inequalities. Replace the inequality symbol with an equal sign. Graph the resulting equation, but since your inequality symbol does NOT include equals, graph the line with a dashed line.

Replace the inequality sign on each inequality with an equals sign. Graph the boundary line. All of your inequalities are geq or leq so use solid boundary lines. After you have graphed each boundary, select a point that is NOT on the boundary. Substitute the coordinate values of the selected point into the original inequality. If the result is a …

You can put this solution on YOUR website! How do you determine which part of the graph you have to shade in, when solving systems of linear inequalities? ` Solve the inequality for x or y, whichever is more convenient. ` If you solve for x, and the inequality starts " x > " or "x > ", shade the area to the RIGHT side of the line. ` If you solve for x, and the inequality starts " x < " or "x ...

In order to graph , we need to graph the equation (just replace the inequality sign with an equal sign). So lets graph the line (simply draw a vertical line through )

Question 851307: Solve each inequality using the test-point or sign graph method.

Question 148204: solve the inequality 6+3y<4 (3-x) for y and graph the solution. Please show me this step by step because I think I went wrong somewhere down the line, and I need to see where.
