Answer:
The intersection point is (2,2)
Step-by-step explanation:
First let's find the equation of f(x), using the linear model:
Using the point (0, 6), we have:
Using the point (3, 0), we have:
So we have that
To find f'(x) (the inverse of f(x)), we can substitute f(x) by x and x by f'(x) in the equation of f(x) and then isolate f'(x):
Now, to find the intersection point, we need to calculate f(x) = f'(x):
And the y-value is:
So the point is (2,2)
