Intersecting Polynomial Functions

Which of the following functions could represent the graph shown?

• f(x) = -2x⁵

• f(x) = -2x⁴ + 7x³ + 3x² -5x + 8

• f(x) = 2x⁵ + 3x⁴ - 3x³ + 5x² - 3x + 4

• None of these functions could represent the graph shown.

Which of the following could be a possible equation for the function shown?

• f(x) =-2x³ + x² - 5x + 1
