The equation will be of the form:

where A is the amount after t hours, and r is the decay constant.
To find the value of r, we plug the given values into the equation, giving:

Rearranging and taking natural logs of both sides, we get:


The required model is:

Answer:

Step-by-step explanation:
we are given a exponential function

we want to figure out the equation of the new graph reflected across the y-axis
remember that,

let y be
so,

hence,
the equation of the new graph
