Answer:
0 ≤ x ≤ 4
Step-by-step explanation:
we are asked to find all the values of x such that y>0.
for y>0, this means that we will only consider the portion of the graph that is above the x - axis (i.e the part of the graph above y=0)
By observation, we can see that the graph is only above the x-axis between the interval 0 ≤ x ≤ 4 (which is the answer to your question)
