Videos and lessons with examples and solutions to help High School students
explain why the *x*-coordinates of the points where the graphs of the
equations *y* =*f*(*x*)
and *y* = *g*(*x*) intersect
are the solutions of the equation *f*(*x*)
= *g*(*x*); find the solutions approximately,
e.g., using technology to graph the functions, make tables of
values, or find successive approximations. Include cases
where *f*(*x*) and/or *g*(*x*) are linear,
polynomial, rational, absolute value, exponential, and logarithmic functions.

- Using technology to graph the equations and determine their point of intersection
- Using tables of values
**Using successive approximations that become closer and closer to the actual value.**
