I didn’t really have a problem with any unit but I just needed to review everything because as we moved on to the next units, I slowly started forgetting the previous ones.
My first question is from the first unit: Series and Sequences, this was the easiest unit for me but the formula I used to answer this question is: 
My second question was on Quadratics and the restrictions on x, for some reason, I always struggled with finding restrictions, now that I learned how to properly do them, they’re really easy for me but I never knew which numbers to actually plug in, so I had to review a few of these questions:
The last question is about finding x-intercepts: this equation was already in general form so I didn’t have to complete the square but I did have to factor it to find the x-intercepts and I showed all my work:
