A group of engineers is building a parabolic satellite dish whose shape will be formed by rotating the curve y=ax2 about the y-a
xis. If the dish is to have a 20-foot diameter and a maximum depth of 2 feet, find the value of a and the surface area (in square feet) of the dish.

TABLE D does NOT represent a linear function
<h2>Explanation:</h2>The Table is shown below. Each table is a relationship between two variables, namely x and y. By plotting each table in a graphing tool we get:
TABLE A, FIRST FIGURE:
It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:
TABLE C, SECOND FIGURE:
It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:
TABLE C, THIRD FIGURE:
It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:
TABLE D, FOURTH FIGURE:
It is not a linear function. It is likely this is a parabola that opens downward.
