Please help with this I need to pass this test or I fail I really appreciate it thank you:(

a because 75 plus 15 equal 90

And we have this for the model:

Now using the other point (3,500)  we have this:

We can divide both sides by 4 and we got:

And if we apply cubic root we got:

So then the model would be:

Step-by-step explanation:

For this case we want to create an exponential function given by this general expression:

And we have the following points (0.4) and (3.500). If we use the point (0,4) we have this:

And we have this for the model:

Now using the other point (3,500)  we have this:

We can divide both sides by 4 and we got:

And if we apply cubic root we got:

So then the model would be:
