• State the intervals that make up the solution set. 1 pc ch 2 2.8 notes day 1 and day 2.notebook November 12, 2013 EXAMPLE
Let f(x) = (x + 3)(x2 + 1)(x 4)2. Determine the real number values of x that cause f(x) to be: • Zero • Positive • Negative Solve 2x3 – 7x2 – 10x + 24 > 0 2 pc ch 2 2.8 notes day 1 and day 2.notebook November 12, 2013 An alternate method
to solve the inequality
is to graph the function
in the coordinate plane. If the inequality is < the solution will
be below the xaxis. If the inequality is > the solution will be above th...
