Answer:
y = 16 
Step-by-step explanation:
Use the given points to find the values of a and b
Using (0, 16), then
16 = a
( = 1 ), thus
a = 16
y = 16 
Using (2, 400), then
400 = 16b² ( divide both sides by 16 )
b² = 25 ( take the square root of both sides )
b = 
= 5
Thus
y = 16 × 
← exponential function
It is $84.6. You multiply 1.6 by 13 which equals $20.8. Then you multiply 3.1 by 14 which equals $43.4. Then you multiply 1.2 by 17 which equals $20.4. Add them together and you get $84.6.
Hope this helps:)<span />
