1. ## function graph

I attached a graph from the problem. Sorry that the graph is so small

Here's the question:
The figure below shows the graph of y=g(x). If the function h is defined by h(x)=g(2x)+2, what is the value of h(1)?

I dont get why the correct answer is 3, and please show steps. THank you thank you thank you in advance!!!

2. $h(1) = g\left( {2\left[ 1 \right]} \right) + 2 = 1 + 2 = 3$

3. Why does g(2[1]) equals 1?

You look at the graph! You tell us what g(2) equals.

5. Oh haha thanks! It equals to one, because when you look at the graph, g(2) is 1.
