Слайд 6Write each inequalities as an equations and solve separately.
Plot the
solutions (called critical x-values) on a number line.
Test an x-value in between the critical values and determine the range that is true for the inequality.
Find the intersection of solutions.
Test an x-value in between the critical values and determine the range that is true for the inequality.
Find the intersection of solutions.
Слайд 8Graph both parabolas first.
Then shade the areas indicated.
The solution
to the system is the part that is shaded by all inequalities.
If there are no overlapping spots, there is no solution .
If there are no overlapping spots, there is no solution .
Слайд 9
Example 2:
.
The overlapped area can satisfy both inequalities.
Thus, it is
the solution to this system of quadratic inequalities
Solve next system
Слайд 10
Example 3:
Solve next system
There is no overlapped area which can satisfy
both inequalities. Thus, there is no solution to this system of quadratic inequalities.
