pre calc project algorithm help

Attached is the reference for this project, and what I have already completed.

What I need done:

-Check for any errors in my work.

– I need my project to look exactly like the reference.

-Add a prediction using the graph, and add comments/ opinions on why you think this is happening.

-Find the vertex, add quadratic function and exponential growth.

– You have to use the powerpoint I gave, cannot be changed.

Thank you!!
