A polynomial function g(x) has a positive leading coefficient. Certain values of g(x) are given in the following table. x –4 –1 0 1 5 8 12
g(x) 0 3 1 2 0 –3 0

If every x-intercept of g(x) is shown in the table and each has a multiplicity of one, what is the end behavior of g(x)?
As x→–∞, g(x)→–∞ and as x→∞, g(x)→–∞.
As x→–∞, g(x)→ –∞ and as x→∞, g(x)→∞.
As x→–∞, g(x)→∞ and as x→∞, g(x)→–∞.
As x→–∞, g(x)→∞ and as x→∞, g(x)→∞.
