4.3 Functions

Would the graph be CONTINUOUS or DISCRETE?
A girl was walking home at a steady pace. Then she stopped to talk to a friend. After her friend left, she jogged the rest of the way home.

• Continuous
• Descrete

Identify the Independent and Dependent Variables, then write a function rule.
A baker spends $6 on ingredients for each cake he bakes.

• Ind: Cost
  Dep: Cakes
  y = 6x
• Ind: Cakes
  Dep: Cost
  y = x + 6
• Ind: Cost
  Dep: Cakes
  y = x + 6
• Ind: Cakes
  Dep: Cost
  y = 6x

CCSS.HSA.SSE.A.1

Write a function rule for the statement.

• y = 2 – x
• y = x – 2
• y = 2x
• y = x/2

Evaluate the function for x = (-1).
y=x²-2x+1

• y =4
• y = 0
• y = 2
• y = -1

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.
