  2. Real World Problem and Variable

  3. Real World Problem Equation • Joe works at a candy store. He makes 50$ a hour. How much does Joe make in a year? ( He works x amount of hours each week.) • Y= 50x(52)

  4. Independent and Dependent Variables Is it a Function? • X is the hours he works while y, is how much he makes in a year. The x is independent because, y=the amount of money he earns a year. While x= the hours he works. In conclusion the amount of money he makes (y) depends on how many hours he works (x). • Yes the problem is a function because the more x increases, the more y will increase. It also is a function because x doesn’t repeat.

  5. Domain and Range

  6. Domain and Range Is the domain continuous or discrete • Domain: Domain is the x value. • Range: Range is the y value. • The domain = x ≥ 0 • The range = y ≥ 0 • The domain is continuous because, the more hours he puts in, the more money he earns.

  7. Function Notation

  8. The equation stated in the problem is y= 50x. Equation Stated

  9. The function notation formula is f(x)=50x. Function Notation

  10. Money E arned Hours Worked
