Answer:
3 because your domain should not repeat
Consider the exponential function 
By definition, the domain of a function is the set of input argument values for which the function is real and defined.
Let we take
then 
then 
then 
If we chose larger values of x, we get larger function values.
For example, If we take 


Thus if we choose smaller and smaller values of x. the f unction values will be smaller and smaller functions.
Thus the domain of the function is the set of all real numbers.
Thus the range is limited to the set of positive real numbers. That is, 
If we choose larger values of x, we will get larger function values, as the function values will be larger powers of 2.
If we choose smaller and smaller x values, the function values will be smaller and smaller fractions.
Answer:
okay, so you put 14/20 as a fraction, and find out the percent. that is 70%. then you find 70% of 100, which is 70.
