Question

What is the equation of the exponential graph shown?

Answer 1

Answer:

$100(0.5)^{x}$

Step-by-step explanation:

According to the graph, the y int is at 100

so that is the starting point

Then at 1 it is at 50

$\frac{100}{50}$ is 2 so that means it is reduced by half

Just to make sure, $\frac{50}{25}$ is also /2 so that means it is the slope

Since it is a decay, the slope has to be less than one so you get the reciprecol of 2 to get....

$\frac{1}{2}$
