Which of the following does NOT represent a direct or indirect negative effect that has resulted from humans’ interactions with our environment? 

Electrons are always evenly distributed.

MULTIPLE CHOICE. Use transformations of a power function to graph f. f(x) = -2(x – 5)5 + 4

Information is given about a polynomial f(x) whose coefficients are real numbers. Find the remaining zeros of f. Degree 5;     zeros: 8, 4 + 5i, -8i

Must show work on paper for full credit. Find all zeros of the function and write the polynomial as a product of linear factors. (Factored form)     f(x) = x4 + 2×3 – 4×2 + 8x – 32 List each zero: [uftdy] f(x) = [igiyyf] polynomial as a product of linear factors

Must show work on paper for full credit. Find the x- and y-intercepts of f. Write all points as ordered pairs. f(x) = (x + 5)(x – 7)(x – 3)2 x – intercept(s): [jhgh] y – intercept: [igig]

MULTIPLE CHOICE. State whether the function is a polynomial function or not. If it is, give its degree. If it is not, tell why not.     

Honorlock will be used for Tests 1-4  and the final exam.

The zinc iodide reaction  will still occur without mixing.

Why was zinc rinsed with water after the color disappeared?
