I need to answer two questions in order to ask a question. sorry that i’m stupid and have no idea how to do this
The y intercept of this function is always (0, a).
This is because when we place 0 in for x (which is the only way it'll be on the y-axis, we get 'a' as a result. This is because of the rule that raising anything to the 0th power will result in the number 1 and multiplying anything by 1 gives us the same number. See the work below for the example.
F(x) = a*b^x
F(0) = a*b^0
F(0) = a*1
F(0) = a
And for an example with a random number, we'll use a = 5 and b = 3
F(x) = 5*3^x
F(0) = 5*3^0
F(0) = 5*1
F(0) = 5
No matter what a and b equal, the intercept will be the a value.

<h3 /><h3>Definition of exchange rate</h3>
Exchange rate is the rate at which one currency is exchanged for another currency. In this question, $1 would be exchanged for 1.26 Canadian dollars.
<h3>Conversion of 15 gallons to liters</h3>
In order to convert 15 gallons to liters, multiply 15 by 3.79
15 x 3.79 = 56.85 liters
<h3>Total cost of of 56.85 liters in Canadian dollars </h3>
56.85 liters x C$1.18 = C$67.083
<h3>Total cost in US dollars</h3>
C$67.083 / 1.26 = $53.24
