The polynomial function that could be represented by the graph is f(x) = x³ + x² - 6x
The attached graph represents the missing part of the question
From the attached graph, the x-intercepts of the graph are:
x1 = -3
x2 = 0
x3 = 2
The equation of the graph is then calculated as:
f(x) = (x - x1)(x - x2)(x - x3)
This gives
f(x) = (x + 3)(x - 0)(x - 2)
Expand
f(x) = x(x² + 3x - 2x - 6)
Evaluate
f(x) = x(x² + x - 6)
Expand
f(x) = x³ + x² - 6x
Hence, the polynomial function that could be represented by the graph is f(x) = x³ + x² - 6x
