Throughout mathematics, we find function notation. Function notation is a way to write functions that is easy to read and understand. Functions have dependent and independent variables, and when we use function notation the independent variable is commonly x, and the dependent variable is f(x).

Anthropologists use the length of certain bones of the human skeleton to estimate the height of the living person. One of these bones is the femur. To estimate the height in centimeters of a female with a femur length of x, the function h(x) = 61.41 + 2.32x can be used. If a 46 cm femur bone is discovered at a dig site, using the height function, estimate how tall the person was that bone belonged to.

  • The x-values of a relation (usually)
  • The output values of a relation
  • The y-values of a relation (usually)
  • Represented on the vertical axis of a coordinate plane
  • Represented on the horizontal axis of a coordinate plane

Vocabulary Review: A function is a relationship that pairs each input value with exactly one output value. Categorize each relationship.

  • Relation A
  • Relation C
  • Relation B
  • Function
  • Not a function

Graph the function rule.


The amount of water w in a wading pool, in gallons, depends on the amount of time t, in minutes, the wading pool has been filling, as related by the function rule w = 3t.

Be sure to include relevant graph detail: label axes, indicate units on both axes, and use arrows to represent end behavior, as appropriate.

To solve an equation we need to undo operations to isolate a variable. So, we need to undo PEMDAS. This means we need to work in a different order.

Put these operations in the order by which you perform them to solve an equation. (first to last)

  1. addition and subtraction (outside parentheses)
  2. multiplication and division
  3. parentheses ( )
Required
4

Put the steps to solving this equation in the right order.

  1. Before we start solving, we identify the variable a, so we can solve for it the variable
  2. the result is x=7
  3. add 7 to both sides of the equation
  4. divide both sides of the equation by 3
Required
10

Solve this equation.

10

Put the steps in the correct order to solve this multistep equation.


  1. undo multiplying by -28 by dividing by both sides of the equation by -28 to get a = 5
  2. Use distribution to multiply (7a+5) by -4 to get -28a - 20
  3. undo subtract 20 by adding 20 to both sides of the equations to get -28a = -140
  4. The solution is a = 5
  5. Check the solution by evaluating the original expression -4(7a+5) to verify that it equals -160
