Question

The following graph shows the functions f(x) and g(x):

Answer 1

The given functions are :
f(x) = x²
g(x) = x² + 5

∴ g(x) = f(x) + 5
g(x) is obtained by shifting f(x) 5 units upward.  See the attached figure

So, The function g(x) is obtained by adding 5 to f(x)

Answer 2

Add 5 would be the correct answer!
