Q43. As f:x= 2x it means the output is 2 times the input (x is input, f:x is output) then the values would be
5-->10
7-->14
-3-->-6
8-->16
Q44. As f:x is 3x-4 it means for every input you multiple by 3 and take away 4 so the values are:
0--> 3(0)-4= -4
2--> 3(2)-4=4
-2(-10+4 divided by 3)-->-10
5(11+4 divided by 3)-->11
