Graphing, using your Graphing Calculator!
Goal: Get Acquainted with how your graphing calculator works – be able to graph simple equations.
Sketch the function here:
1) First do some algebra so you can put these into
your graphing calculator, then graph them (using
your calculator).
2x  3y  7

Solving Equations Graphically
Goal: Get Acquainted with how your graphing calculator works – be able to graph simple equations.
4) Use your calculator to graph the following 5) Use your calculator to graph the following equation:
equation:
2
y   x2
2
3
y   x2
Next, algebraically (i.e., paper and pencil)find the x3
Next, use the zero command to find the x
intercept(s) for the equation. SHOW ALL WORK!
intercept(s). What is the x-intercept?
6) Use your calculator to graph the following
equation:
y  1 x
2
Next, use the zero command to find the x intercept(s).
What are the x-intercepts?
7) Use your calculator to graph the following equation:
y  1 x2
Next, algebraically (i.e., paper and pencil)find the xintercept(s) for the equation. SHOW ALL WORK!
If there are multiple x-intercepts, how many will the
TI-83 find for you each time you use the zero
command?
8) Use your calculator to graph the following
equation:
2
3 x  x  2
3
Next, use the intercept command to find the value(s)
of x.
9) Use your calculator to graph the following equation:
2
3 x  x  2
3
Next, algebraically (i.e., paper and pencil) find the value(s) of
x. SHOW ALL WORK!
10) Use your calculator to graph the following equation:
2
3  x2  x  2
3
Next, use the intercept command to find the value(s) of x.
If there are multiple points at which the two sides cross, how many points will the TI-83 find for you each time
you use the intercept command?
