Answer:
[1,∞)
Step-by-step explanation:
I graphed the function you provided using the free online graphing calculator, DESMOS.
The image provided below is an image of the graph.
We can see the the smallest y-value is 1 and it is included on the graph. Another observation is that the y-values infinity increase in value, starting from x=4. Therefore, the ending value of the range should be ∞, and this is not included on the graph.
