Question

1) What coordinate needs to be removed for this graph to be a function? (-3,5) 5 5 2 a (1.-3) © 13.2) O (2.1)

Answer 1

EXPLANATION.

The point that must be removed is (3,2) since it is outside the function and does not correspond to the figure formed by the function, which is a curve.

If we look carefully at the graph, each of the points when joining them forms the figure that is a curve.
