Question

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 1

Answer: (b) g(x) = x² + 4

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
