Answer:
Step-by-step explanation:
y=4 times 1/2 to the power of x can be written symbolically as
                                                              4                  4
y = 4(1/2)^x.  This is the same as y = ------- or y = -------- * 2^(-x)
                                                              2^x                1
This function is a "decaying exponential."
A suitable table follows: 
x      4(2^[-x])         x    y
0      4(2^0)           (0, 4)
1        4(2^1)            (1, 8)
2       4(2^2)           (2, 16)
and so on.

c. Measuring the differences in blood pressure before, during, and after a procedure.
Step-by-step explanation:
Quantitative research use instruments to measure the variables we are studying. You could measure the variable by using any instrument, in this case the blood preasure during a procedure could be measured with an instrument called sphygmomanometer. Other options couldn't be measured with any instrument.
 
        
             
        
        
        
The total number of points scored on the test woukd be 200. the independent variable would be x, or the number of questions answered correctly. the dependent would be the points scored because the points scored depends on how good you did on the test.
