Answer:
4 meters
Step-by-step explanation:
Given that :
Initial elevation of butterfly = 20 meter
Change in elevation from initial height = negative 16 m = - 16 meter
Final elevation can be obtained by taking the sum of initial elevation and the change in elevation
(20 m + (- 16 m))
(20 m - 16 m)
= 4 meters
Y = 5.50x + 21...where x is the number of months and y is the total cost
function notation is basically subbing in f(x) for y
so ur rule in function notation is : f(x) = 5.50x + 21 <==
