Identifying Steps to Model and Solve Problems. When modeling scenarios with linear functions and solving problems involving quantities with a constant rate of change, we typically follow the same problem strategies that we would use for any type of function.Let's briefly review them: Identify changing quantities, and then define descriptive variables to represent those quantities.
Solve applied problems involving rational functions. In Example 2, we shifted a toolkit function in a way that resulted in the function \displaystyle f\left (x\right)=\frac {3x+7} {x+2} f (x) = x + 23x + 7. This is an example of a rational function. A rational function is a function that can be written as the quotient of two polynomial ...
According to Alice Hoffman every problem has a solution. In finding the solution one important aspect to consider is the "how" or the process of finding it. In solving problems involving functions there are different process that we can employ to attain the solution. Hello! A certain cellphone company offers a plan that costs ₱1,200 per ...
Evaluating and Solving Functions
Evaluating Functions Expressed in Formulas. Some functions are defined by mathematical rules or procedures expressed in equation form. If it is possible to express the function output with a formula involving the input quantity, then we can define a function in algebraic form. For example, the equation [latex]2n+6p=12[/latex] expresses a functional relationship between [latex]n[/latex] and ...

Solving Functions from Word Problems
f(x) = 0.75(x − 1) + 5. Correct answer: f(x) = 0.75(x − 1) + 5. Explanation: Notice that the question describes a linear equation because there is a constant rate of change (the cost per topping). This means we can use slope intercept form to describe the scenario. Recall that slope intercept form is. y = mx + b.
