Answer:
Step-by-step explanation:
So, we have the graph y=f(x).
And we want to find:
Remember that the inverse of a function is simply the x-values and y-values swapped. To see this, let's let our inverse equal y:
This means that we have the point:
So, to find our solution, we will swap the x- and y-coordinates. This gives us:
So, simply need to find the x-coordinate such that y is 0.
From our graph, we can see the point (6,0). In other words:
So:
And we're done!
Answer:
Step-by-step explanation:
As this is the case of exponential growth, we can use the function
Here A is function of t, where A gives the balance after time t.
P = initial deposit,
r = rate of change or rate of interest,
$6200 deposit that earns 8.4% annual interest compounded monthly for 18 months.
So,
P = $6200,
r = 8.4% annual = monthly =
monthly (as interest compounded monthly)
t = 18 months,
Putting all the values,
