Let f(x)=4^x and g(x)=x+3 the graph of (f o g)(x) is shown below. What is the range of (f o g)(x)?

Answer:
y>0
Step-by-step explanation:
The range refers to all values of y for which x is defined.
We can see from the graph that the line y=0 is a horizontal asymptote to the curve and the graph increases from left to right without bounds.
Therefore the range is all positive y-values.
We can write all positive y-values as y>0
The first choice is correct
