Question

Consider the Piece-Wise graph described by the following equation:

Determine the coordinates of the point on the graph where x=3.

(3, 1)

(3, 3)

(3, 5)

(3, 13)

Answer 1

(3, 5 )

Explanation:

when x = 3, that is x ≥ 3, thus

y = 2x - 1 = 2(3) - 1 = 6 - 1 = 5 ⇒ (3, 5 ) is the point on the graph
