Identifying Characteristics of Quadratic Functions

Identifying Characteristics of Quadratic Functions 1.16 - Solution

arrow_back Return to Identifying Characteristics of Quadratic Functions
a

The function's vertex is found at the function's highest or lowest point.

In this case it's the lowest point and can be read as

b

For quadratic functions, the axis of symmetry always goes through the vertex. Read the -coordinate of the vertex and you'll find the axis of symmetry.

The -coordinate is so the axis of symmetry is

c

The function's zeros is where the value of the function is , so the -values when the curve intersects the -axis.

The zeros are and
