Does the value of c in the quadratic function y = ax2 + bx + c affect the vertical position of the vertex of the graph? explain why or why not.
a. no; the position of the axis of symmetry and hence the vertex point is affected only by the values of a and b.
b. yes; changing the value of c shifts the entire graph, including the vertex point, up or down.
c. no; changing the value of c shifts entire graph left or right. it does not affect the vertical position of the vertex.
d. yes; increasing c shifts the vertex point down.

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,
