Example 2.7.4. Graph and give the interval notation equivalent: x < 3 or x ≥ − 1. Solution: Both solution sets are graphed above the union, which is graphed below.
Graphing Linear Inequalities - Math is Fun
WebThe circle will be open because it does not contain the 5 because x is "greater than" 5. x has to be greater than 5, so 5 is not an answer to the inequality. Now if your hand is closed around an item you can contain it within your hand. For an inequality example, let's use 2 ≥ x. the circle is closed because 2 is contained and agrees with the ...

How do you graph y is greater than or equal to 2
WebFeb 6, 2024 · Since y > − 2 has > as the inequality symbol, you must then graph y=−2 as a dashed line. You must then determine where to shade. Since y > − 2 is stating that y must be BIGGER than −2, you must then shade above the boundary line. This is because all the points above the boundary line have yy-coordinates that are bigger than −2. WebFeb 17, 2024 · The range for this one is all real numbers less than or equal to -2. And the range for this graph is all real numbers greater than or equal to -3. As you can see, the turning point, or vertex, is part of what determines the range. The other is the direction the parabola opens. If a quadratic function opens up, then the range is all real numbers ... WebOct 1, 2024 · PiaDeveau. Let us check the slope of y-intercepts of the given lines in the graph first. The y-intercept of above line is 1 and slope of. Rise/run = 2/1 (Moving 2 units up and 1 unit right). So, the equation should be. y=2x+1. Y-intercept of second line is -2 and slope is. Rise/run = -1/1 (Moving 1 unit down and 1 unit right). canon battery grip for r5
