Question

At a grocery store, the number of customers arriving per hour is shown by the function f(x) = 2 (to the x+1 power). Find the number of customers that arrived in the 6th hour.

Answer 1

f(6) = 2^x+1

f(6) = 2⁶⁺¹

f(6) = 2⁷

f(6) = 2 · 2 · 2 · 2 · 2 · 2 · 2 

f(6) = 128

 

One hundred twenty-eight customers arrived in hour six.
