Select the domain and range of the function f (x) = 7x". O A) The domain is {x|x > 0), and the range is all real numbers.
OB) The domain is {x|x > 0), and the range is {f(x)]f(x) > 0).
o C) The domain and range are both all real numbers.
OD) The domain is all real numbers, and the range is {f(x)]f(x) > 0).

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
