Answer: C. y=[x]+3
Step-by-step explanation:
Let g(x) be the function of the given graph.
For which, the parent function is,
f(x) = [x]
In which, f(x) = 0 in the interval [0, 1)
But, according to the graph,
In the interval [0,1), g(x) = 3
⇒ F(x) is shifted vertically upward,
⇒ g(x) = f(x) + 3
⇒ g(x) = [x] + 3
Therefore, Option C is correct.
