Question 1130136
Below is the graph of x^2 + 4y^2 =16. Write the distance from (0,0) to (X,Y) as d(x), as a function of x. The picture is of a circle with a line. The line goes from the right side of the circle which is point (x,y) to the center point which is (0,0). D(x) is in the middle of the line.
----------
email a sketch or photo of the graph.
x^2 + 4y^2 = 16 is not a circle.
