Use the equation to predict y when x = 10. ________
a. quadratic
b. 109.55
c. cubic
d. y = 0.29x^3 - 2.48x^2 + 6x + 7.55
e. 93.75
f. y = -2.3x^2 + 8.2x + 6.32

Answer

  1. Based on the scatter plot, the best model is cubic (option c).

  2. Find the equation of the line of best fit: y = 0.29x^3 - 2.48x^2 + 6x + 7.55 (option d).

  3. Use the equation to predict y when x = 10: 93.75 (option e).
