Answer:
The choice that matches the graph of the function as is defined to us is:
Graph A.
Step-by-step explanation:
We are given a function f(x) as:
f(x)= 2x if x < 3
and 4 if x ≥ 3
This means that in the region (-∞,3) the graph of a function is a straight line that passes through the origin and has a open circle at x=3.
and in the region [3,∞) the graph is a straight horizontal line i.e. y=4.
Hence, the graph of this function is:
Graph A.
