Across
- 2. x-coordinate of a point at which the relation crosses the x-axis, meaning the y-coordinate equals zero, (x, 0)
- 3. set of output values for the dependent variable over which the function is defined
- 6. set of input values for the independent variable over which the function is defined
- 8. equation of best fit representing a set of bivariate data. Calculators find the equation of regression by calculating the lowest sum of the squares of differences in the predicted values and the observed values.
- 10. regression used to determine the exponential function that is the best fit for the data. The exponential regression function on the graphing calculator can be used to calculate the best exponential function to model the data.
- 11. table of values of collected data
- 13. a relationship between two variables, x (independent) and y (dependent), that always has a constant, unchanged ratio, k, and can be represented by
- 14. correlation coefficient and inferences
Down
- 1. line graph or scatterplot
- 4. regression used to determine the linear function that is the best fit for the data. The linear regression function on the graphing calculator can be used to calculate the best linear function to model the data.
- 5. y-coordinate of a point at which the relation crosses the y-axis, meaning the x-coordinate equals zero, (0, y)
- 7. if temperature is constant, then pressure of an ideal gas is inversely related to the volume of the gas. Boyle’s Law is represented by where P is the pressure on a volume of gas and V is the volume of the gas.
- 9. a linear relationship between two variables, x (independent) and y (dependent), that always has a constant unchanged ratio, k, and can be represented by y = kx
- 12. the force required to stretch or compress a spring a given distance is directly proportional to the distance. Hooke’s Law is represented by f = kx, where f is the amount of force, k is the constant factor associated with the spring (stiffness)
