Across
  1. 4. not in a line (function has an exponent greater than one on the independent variable)
  2. 9. the vertical axis in the coordinate plane
  3. 10. a set of ordered pairs
  4. 12. the dependent variable, usually y
  5. 13. the variable whose value is determined by the independent variable. The output.
  6. 14. the independent variable, usually x
  7. 16. the variable that stands alone. it affects the value of the dependent variable. The input.
Down
  1. 1. the size of a quantity
  2. 2. a relation in which every input has exactly one output
  3. 3. a place at which a relation begins when the independent variable has a value of 0 this is the value of the function. Exaples: starting price, initial fee, where the function begins, the y-intercept
  4. 5. the act of replacing a variable with its value and evaluating an expression
  5. 6. the value of a function or relation when the input is 0 (x=0 y-value is y-intercept or initial value)
  6. 7. the place where the x- and y-axes intersect (0,0)
  7. 8. the sent of numbers (x,y) that defines a location in the coordinate plane
  8. 11. one way to represent a relation showing inputs and outputs and how they are related
  9. 15. the horizontal axis in the coordinate plane
  10. 17. in a line (function has an exponent of 1 on the independent variable)
