Which of the following is not a function
aleksandr82 [10.1K]

Answer:

The ellipse is not the graph of a function.

Step-by-step explanation:

If you can draw a vertical line on the graph that intersects the graph in two or more points, the relation shown is <em>not a function</em>.

A vertical line will intersect the ellipse at two points (unless it is tangent to an end of the major axis), so the ellipse is not the graph of a function.

The numerical values we give to π or e or any root, logarithm, trig function, and polynomial solution are, of necessity, rational approximations to the true value. An "exact" value for an irrational number cannot be written down, so it must be approximated any time its numerical value is needed.
