Answer:
1) Option A
2) Option C
3) Option A
Step-by-step explanation:
We have given that : function 
1) If the graph of the given function were shifted six units to the left
translation to left means b unit is add on the function
i.e f(x)=f(x+b)
Therefore,the new graph have the function 
so, Option A is correct
2) If the graph of the given function were shifted upward by six units
translation to upward means b unit is add to the function
i.e f(x)=f(x)+b
Therefore,the new graph have the function 
so, Option C is correct
3) 1.5 times of the x-values of the function 
1.5 times of the x-values means 1.5x = 3x/2
Therefore, 
So, Option A is correct
