SP 3 Unit I Concept 1 Exponential Functions


 This problem is to show my understanding about graphing exponential functions. It shows how to identify the x-intercept, y- intercept, domain, and range. This problem is to show when there wouldn't be an x-intercept on an exponential function and how the asymptote affects the graph. 

The viewer needs to pay special attention to why the x-intercepts do not work in this exponential function. They also need to pay attention to asymptote and how that affects the graph. The domain and range also help with the restrictions of the graph. The viewer should also see how the y-intercept is solved for. 


Steps
1. Seperate the equation into A,H,B,K 
2. Began solving for x-intercept by setting y=0 
3. Notice that it can't be done because you can't take 
the In of a negative number 
4. Head to y-intercept
5. Plug in zero for x 
6. Use pemdas to correctly solve the y-intercept. 
7. Began choosing keypoints.
8. Plug equation into calculator and look up the points
8. Write the asymptote which is also K remember y=#
9. Draw the asymptote on the graph. 
10. Write out domain and range 
11. Do it correctly. 
12. Plot points on graph. 
13. Draw a line and you're done.
