Answer:
y=3(x-9)^2+4
Step-by-step explanation:
To move a parabola horizontally to the right, subtract 9.
To move it upward 4 units, you simply have to add 4.
These do not change the characteristics of the shape. I suggest looking at a set of rules that affect how the parabola moves horizontally and vertically.
U divide 330 by 15 and get the quotient then do the same thing to 20 and add the quotients together to solve for x and y
The average rate of change is calculated as the slope of the line between the two points on the graph. Since at x = 1, y = -3, and at x = 3, y = 1, these are the two points which we calculate the slope from. Using the formula
m = (y2 - y1)/(x2 - x1)
m = (1 - (-3))/(3 - 1)
m = 4/2
m = 2
Therefore the slope, or the average rate of change, between these points is 2.
