2. DEFINTIONS
The y – intercept is the point(s) where the graph
touches or crosses the y – axis
The x – intercept is the point(s) where the graph
touches or crosses the x – axis
The x – intercepts are also called the zero(s) of the
function
3. ZERO-PRODUCT PROPERTY
The zero – product property can be used to solve
some quadratic equations in standard form.
The Zero – Product Property
If ab = 0, then a = 0 or b = 0
Steps to Solve:
1. Factor the quadratic
2. Apply the Zero – Product Property:
Set each factor = 0 and solve for the variable
