WebThis compound inequality is true for values that are both greater than zero and less than four. Graphically, we represent it like this: So, in this case, 2 2 is a solution of the compound inequality, but 5 5 is not because it only satisfies one of the inequalities, not both. WebThe simplest Quadratic Equation is: f (x) = x 2 And its graph is simple too: This is the curve f (x) = x2 It is a parabola. Now let us see what happens when we introduce the "a" value: f (x) = ax2 Larger values of a squash the curve inwards Smaller values of a expand it outwards And negative values of a flip it upside down Play With It the philippines owns the scarborough shoal

WebTo plot an inequality, such as x>3, on a number line, first draw a circle over the number (e.g., 3). Then if the sign includes equal to (≥ or ≤), fill in the circle. If the sign does not include equal to (> or <), leave the circle unfilled in. Finally, draw a line going from the circle in the direction of the numbers that make the inequality true.
