To describe the end behavior of a quadratic function, we generally consider the standard form of the quadratic function, which is \( f(x) = ax^2 + bx + c \).
1. If the leading coefficient \( a > 0 \):
- As \( x \) approaches \( -\infty \), \( f(x) \) approaches \( +\infty \).
- As \( x \) approaches \( +\infty \), \( f(x) \) approaches \( +\infty \).
2. If the leading coefficient \( a < 0 \):
- As \( x \) approaches \( -\infty \), \( f(x) \) approaches \( -\infty \).
- As \( x \) approaches \( +\infty \), \( f(x) \) approaches \( -\infty \).
Please apply the above rules based on the specific function's leading coefficient you are analyzing:
- If \( a > 0 \):
- As \( x \) approaches \( -\infty \), \( f(x) \) approaches \( +\infty \).
- As \( x \) approaches \( +\infty \), \( f(x) \) approaches \( +\infty \).
- If \( a < 0 \):
- As \( x \) approaches \( -\infty \), \( f(x) \) approaches \( -\infty \).
- As \( x \) approaches \( +\infty \), \( f(x) \) approaches \( -\infty \).
You can fill in the blanks in your description based on the sign of \( a \) once you identify the leading coefficient of your quadratic function.
