MP REASONING Explain why a V-shaped graphERROR ANALYSIS In Exercises 13 and 14, describe ar correct the error in determining whether the table of graph represents a linear function. 13. X 2 +2 X 2 6 4 16 64 256 As xincreases by 2, yincreases by a constant factor of 4. So, the function is linear. 14. X 2 -2 -2 The graph is a line. So, the graph represents a linear function.In Exercises 15-22, determine whether the equation represents a linear or nonlinear function. Explain. Example 3 15. y - x3+ 13 16. y = 7- 3x 17. y = V8 - x 18. y = 4x(8 - x) 19. 2 + y = 3x + 4 20. y - x = 2- i 21. 18x - 2y - 26 22. 2r + 3y - 9xy 23.
