Quadratic Functions and Characteristics

Define Axis Of Symmetry

• A line that divides the graph into two equal parts. i.e. cuts the graph in half

• Where the parabola touches or intersects the x-axis, also called the x-intercept

• The highest y-value on the graph

• The highest or lowest point on the graph

What are the X-intercept(s) of this graph?

• -1 and -3

• 1 and -3

• 1 and 3

• -1 and 3

Find the axis of symmetry for
f(x) = x²- 8x + 15.

Find the axis of symmetry and vertex

• x=3 (3,-3)

• x=4, (4,-4)

• x= -4, (-4,4)

• x=-4 (-4, 60)

The axis of symmetry line passes through which point?

• y-intercept

• any random point
