Which function below has a graph that is a translation up of 3 units of the graph of f(x)=x^2 +1?(Need answer in less than 2 hours!)

Answer: (b) g(x) = x² + 4
Step-by-step explanation:
Consider the equation f(x) = x² + 1
when translating UP, we change the y-intercept by adding 3 to that value.
g(x) = x² + 1 + 3
= x² + 4
