Question

DETERMINE WHETHER THE GRAPH SHOWN TO THE RIGHT REPRESENT A FUNTION

Answer 1

Step 1

If a vertical line intersects a curve on an xy-plane more than once then for one value of x the curve has more than one value of y, and so, the curve does not represent a function. If all vertical lines intersect a curve at most once then the curve represents a function.

Step 2

Final answer

B.
