Equation and Function Rules

What is a function rule?

• Rules that function

• The law

• Describes the relationship between the input (x) and the output (y)

The "X" value is the OUTPUT value.

• True

• False

An equation is a math ​ (a)   with an ​ (b)   , ​ (c)   and/or ​ (d)   .

• phrase
• equal sign
• numbers
• variables

Simplify the following expression:
3 + 5x + 8 - 2x

• -3x² - 11
• 3x² + 11
• 11 - 3x
• 11 + 3x

Solve for x:
5 + 3x = 8x - 15

• 10
• 4
• 2
• 20/11

Find the function rule for the function table.

• 2/n
• n + 2
• 2n
• n - 2

Write the function rule for the following table.

•  5x
• 5x + 1
•  x + 5
•  x + 1

Find the function rule.

• y = 2x

• y = 2x+3

• y = 3x+3

• y = -2x+3

The output is four times the input.

• y = x/4
• 4x
• y = 4x
• y = x +4
