What can be determined by looking at the polynomial f(x)=(x+3)(x−7)? A. The graph of the polynomial has a vertex at (3,−7). B. The graph of the polynomial has a vertex at (−3,7). C. The graph of the polynomial has zeros at (3,0) and (−7,0). D. The graph of the polynomial has zeros at(−3,0) and (7,0).

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

answer: 8

step-by-step explanation: if you add the possibilities 5 different flavor and 3 different sizes 5+3=8

sweetheart, there isn't a cube below.
