Name Honors Algebra 2 January 10, 2011 “Zeros and solutions” day 2 page 1 Zeros and solutions (continued) The important connection f ( x ) = g ( x ) is equivalent to f ( x ) – g ( x ) = 0. The solutions to the are the same as the zeros of the equation f ( x ) = g ( x ) function f ( x ) – g ( x ). How to find zeros on your calculator The zeros of a function appear as x -intercepts on the function graph. (Why?) Here is how you find these zeros on your calculator. Press “y=” and enter the function. Press “graph” and see how many zeros there are. For each zero, do the following: Press “calc” and choose 2:zero Move the cursor to the left of the x -intercept, and press “enter”. Move the cursor to the right of the x -intercept, and press “enter”. Move the cursor anywhere close to the x -intercept, and press “enter”. The x -coordinate now displayed is the zero. More problems 6. a. Fill in the missing values in this table of values. (In some cases, more than one number will fit, and you may choose any of them.)

###### "Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
