Function value

Question

The graph of the absolute value function f(x)=|x+9|+1 is shown in the graph.

Drag and drop the numbers to identify the vertex and equation for the axis of symmetry.

vertex( , )

Axis of Symmetry: X=

**numbers may be repeated if needed**

-9, -1. 1, 9

Answer 1

vertex is (-9, 1)

the x coordinate of the vertex is the value of x that makes |x+9| = 0

axis of symmetry is a vertical line through the vertex, x =-9

y coordinate of the vertex is the value of f(-9) = 0 + 1 = 1

Answer 2

See the graph below... the Vertex is where at (-9,1) which would place your axis of symmetry at x=-9
