Round your answers to two decimal places (c) use your table to determine whether , increases or reases as . gets larger as gets larger

Solution

a) y = 5sqrt(x)

y is proportional to the positive power of x

b) x = 1 ; 10 ;100;1000

   y = 5sqrt(1) ; 5sqrt(10) ; 5sqrt(100) ; 5sqrt(1000)

      = 5 ; 15.81 ; 50 ; 158.11

y increases when x increases
