The graphs below have the same shape. What is the equation of the red
graph?
f(x) = x

Answer:
C
Step-by-step explanation:
Given f(x) then f(x) + c represents a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Here g(x) is the graph of f(x) shifted up by 4 units, thus
g(x) = x² + 4 → C
