Answer:
y = 4
Step-by-step explanation:
The form of the exponential function is y = a 
Use the given points to solve for a and b
Using (0, 4 ), then
4 = a
( = 1 ), thus a = 4
y = 4
Using (2, 196 ), then
196 = 4b² ( divide both sides by 4 )
49 = b² ( take the square root of both sides )
b = 
= 7
y = 4 ← exponential function
Answer:
Store A
Step-by-step explanation:
Store A costs $200.
Store B costs $240, with a 15% discount.
To solve how much the discount is, you do -
Since Store A is still cheaper, choose Store A.
Answer:
i think it is B
Step-by-step explanation:
because that one isn't really a rate as much as the other ones are, its more of a ratio, i'm bad at explaining things, hope its correct :D
