Question 1045928
to be continuous..need to look at when x = -2 and x-1
when x = -2
x + 2p = 3px + q
Substitute x = -2
-2 + 2p = -6p + q
-2 = -8p + q  ****
when x = 1
3px + q = 3x - 2q
Substitute x = 1
3p + q = 3 - 2q
3p + 3q = 3  ***
____________________
-8p + q = -2
3p  +3q  = 3
__________________ Multiplying 1st by -3 to eliminate q when adding both
27p = 9
p = 1/3
q = 2/3
