Answer:
Step-by-step explanation:
Notice that the red graph is the blue graph shifted 1 units up.
According to the function transformation rules, we add to the output of the function to shift its graph units up, and we subtract to the output of the function to shift its graph units down.
The output of our function is , and since we want to shift 1 units up, . In other words, we just need to add 1 to the output of the function:
We can conclude that the equation of the red graph is .
