The students will investigate the importance of
manipulating symbols in order to solve problems while
using the necessary algebraic skills required to
simplify algebraic expressions and solve equations and
inequalities.
Students will also apply more than one appropriate
method to solve a quadratic equation.
To finish out Unit Five, students will investigate and
model situations for functions that are neither linear
nor quadratic models.
Critical Questions:
- How can you decide if a relationship is linear,
quadratic or exponential by looking at its graph?
- How can you decide if a relationship is linear or
quadratic by looking at its symbolic representation?
- When might you use a table to answer a question
about a linear or quadratic relationship?
- What do the x-intercepts represent in a quadratic
graph and why is that important?
