• Not a polynomial function

• No, it is not a polynomial function.

Describe the end behavior of the graph of the function. f(x) = 7x^6 - 8x - 5x^4

• As x approaches infinity, f(x) approaches infinity and as x approaches negative infinity, f(x) approaches negative infinity.

• As x approaches infinity, f(x) approaches infinity and as x approaches negative infinity, f(x) approaches infinity.

• As x approaches infinity, f(x) approaches negative infinity and as x approaches negative infinity, f(x) approaches infinity.

• As x approaches infinity, f(x) approaches negative infinity and as x approaches negative infinity, f(x) approaches negative infinity.

• None of the above

Simplify the expression: (3x - 2)(6 - x)(9 - 2x)
