Evaluating Piecewise Functions From a graph

Evaluating Piecewise defined functions from a graph works much like the problems we did at the beginning of class.

We want to put our mouse on the x-value and go up or down until we hit a line or a closed circle. find f(3)

find f(5)

Multiple Choice

What was f(5)

• 5

• 6

• 7

• 8

find f(-4)

Multiple Choice

f(-4)

• 2

• 4

• 5

• undefined

• find f(-2)

Multiple Choice

f(-2)

• -5

• 1

• 2

• 3

find f(-1)

​

Multiple Choice

f(-1)

• 4

• 3

• 2

• -1
