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
