### Problem 5

State the degree and end behavior of \(f(x)=4x^3+3x^5-x^2-2\). Explain or show your reasoning.

### Solution

### Problem 6

Select **all** the polynomial functions whose graphs have \(x\)-intercepts at \(x=4,\text-\frac14,\text-2\).

\((x+4)(4x-1)(x-2)\)

\((x-4)(4x+1)(x+2)\)

\((x-4)(4x-1)(x-2)\)

\((x+4)(4x+1)(x+2)\)

\((2x+4)(4x - 1)(x-2)\)

\((4x-16)(4x + 1)(x + 2)\)
