Identifying Functions: Advanced Concepts

What is the output when an apple is put into the bakery machine?

• Cherry Pie

• Muffin

• Juice

• Apple Pie

Why is the relationship not a function when the apple produces both pie and juice?

• Because the inputs are not fruits

• Because the outputs are not baked goods

• Because the machine is broken

• Because one input leads to multiple outputs

What is the output when the input is 5 in the function y = 2x + 1?

• 13

• 10

• 12

• 11

How do you determine the output value in a table for the function y = 2x + 1?

• By guessing

• By looking at the graph

• By using a calculator

• By plugging the input value into the equation

Is the equation y = x^2 a function?

• No, because it has multiple outputs for the same input

• No, because it is a quadratic equation

• Yes, because each input has a unique output

• Yes, because it passes the vertical line test

What is the output when the input is 2 in the function y = x^2?

• 6

• 4

• 8

• 2

Why is y = sqrt(x) not a function?

• Because it has no outputs

• Because it has multiple inputs

• Because it is not a linear equation

• Because one input leads to multiple outputs

What is the output when the input is 9 in the function y = sqrt(x)?

• 3 and -3

• 9

• 0

• 1 and -1

Which of the following tables represents a function?

• A table where each input has no output

• A table where each output has multiple inputs

• A table where each input has a unique output

• A table where each input has multiple outputs

What is the output when the input is 3 in a function table where each input has a unique output?

• 5

• 7

• 9

• 80
