Graphing quadratic inequalities ppt
WebQuadratic Inequalities When solving inequalities we are trying to find all possible values of the variable which will make the inequality true. Consider the inequality We are trying to find all the values of x for which the quadratic is greater than zero or positive. 5 Solving a quadratic inequality We can find the values where the quadratic equals WebKey points • First replace the inequality sign by = and solve the quadratic equation. • Sketch the graph of the quadratic function. • Use the graph to find the values which satisfy the quadratic inequality. Example 1 Find the set of values of x which satisfy x 2 + 5 x + 6 > 0 x 2 + 5 x + 6 = 0 x + 3)( x + 2) = 0 x = −3 or x = −2 x

WebThe graph of a quadratic function is a parabola, which is a "u"-shaped curve: A coordinate plane. The x- and y-axes both scale by one. The graph is the function x squared. The function is a parabola that opens up. The function decreases through negative two, four and negative one, one. The vertex of the function is plotted at zero, zero, then ...
