For each increment in x, the output is multiplied by 2. The function could be written the way a geometric sequence can be written:
... f(x) = 5·2^(x-1)
Or, it could be simplified to ...
... f(x) = (5/2)·2^x
The first 5 terms will be
... 5, 10, 20, 40, 80
Although theoretically there are infinite lines in space and in a plane, too, at least three non collinear points are necessary to define a plane. Two intersecting lines will therefore be necessary to define it (two points create a line); these intersecting lines are the ones to help define coordinates (x,y).

Given that there is a survey of 100 randomly selected female members of the gym about choosing between "easy weight-lifting machines or the harder free weights".
Report of the survey says that "female members at the gym prefer the weight-lifting machines over the free weights."
Now we have to select from the given statements that correctly evaluate the report.
According to me "The question is biased towards a response of preferring to use weight-lifting machines." because description of word "hard" is used for "free weights" while word "easy" is used for "machines". That may persuade some people to choose the machine.
Since 100 females are randomly selected not specifically so "The sample is not biased."
Hence final answer should have two statements:
1) The question is biased towards a response of preferring to use weight-lifting machines.
2) The sample is not biased.
