The answer for this problem is 7
ANSWER
y=x
y=x³
EXPLANATION
A function, f(x) has an inverse if and only if

Thus, the function is one to one.
For y=x or


Hence this function has an inverse.
For the function y=x² or f(x)=x².

This function has no inverse on the entire real numbers.
For the function y=x³ or f(x)=x³

This function also has an inverse.
For y=x⁴ or f(x) =x⁴

This function has no inverse over the entire real numbers.
You would convert 500 inches to centimeters, which is 500 times 2.54= 1270, then divide that by 365 days, leaving you with an answer of 3.47945205479, or just 3.47 centimeters.
K(x)=moles
p(x)=rollls
subsitute k(x) for x in p(x)
p(k(x))=2(x-1)+3=2x-2+3=2x+1
that is
p(x)=2x+1 for
p(x)=rolls
and x is toes
