Question

How would you describe the difference between the graphs of f(x) = x2 +4 and
G(y) = y2 +4 ?

Answer 1

They're the exact same, except for the variables.

Explanation:

Since the variable can be any letter, it is the exact same equation but with different letters as x. Although the equation of G(y) has a y instead of x, you know y is the x and g(y) is the y because the y inside of the parentheses tells us that y is the independent variable.
