Discussion:

f(x) = 3x2 - 2x + 5

Substitute x = -2  in f(x) above to get

f(-2) =

3 (-2)^2 - 2(-2) + 5 =                  => (-2)^2 = (-2) * (-2) = +4, -2(-2) + + 4

3*4 + 4 + 5 =

12 + 4 + 5 =

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
