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.
Categorize each representation of a relation on the left based on its type.

Consider the relation {(-2, -3), (-1, 4), (0, 5), (1, 6)}.
Represent the relation with a mapping diagram. Remember to label the domain and range in your diagram.
Vocabulary Review: A function is a relationship that pairs each input value with exactly one output value. Categorize each relationship.

What is f(2) for the function f(x) = 4x + 1?
Use the function w(x) = 250x, which represents the average number of words a person can read in one minute to determine many words the average person can read in 6 minutes. Enter only a number.
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)
multiplication and division
parentheses ( )
addition and subtraction (outside parentheses)
Put the steps to solving this equation in the right order.
divide both sides of the equation by 3
add 7 to both sides of the equation
the result is x=7
Before we start solving, we identify the variable a, so we can solve for it the variable
Solve this equation.
Put the steps in the correct order to solve this multistep equation.
undo multiplying by -28 by dividing by both sides of the equation by -28 to get a = 5
Use distribution to multiply (7a+5) by -4 to get -28a - 20
undo subtract 20 by adding 20 to both sides of the equations to get -28a = -140
The solution is a = 5
Check the solution by evaluating the original expression -4(7a+5) to verify that it equals -160
