Answer:
YES
Step-by-step explanation:
Most real numbers (points on the number-line) are irrational (not rational). The rational numbers are those which have repeating decimal expansions (for example 1/11=0.09090909..., and 1=1.000000...=0.999999...) . They are also those which have terminating continued fraction expansions.
Part A. Yes, because y=f(x)=x⁵.
Part B. f(4)=2(4)+12=8+12=20.
I/3 of 123 is 41
41 dollars are taken off, so 123-41=82
the sale price is 82 dollars
