The domain of a function can be thought of as the set of "x" values for which it is defined. So Choice C is the correct answer. (Note that choice A is NOT the answer as it contains (x,y) pairs, not single "x" values)
The formula is A=p (1+rt) A future value 2408 P present value 1400 R interest rate? T time 12 years Solve the formula for r R= ((A/p)-1)÷t R=((2,408÷1,400)−1)÷12 R=0.06×100 R=6%
