Given the function g(x) = (x + 3)^2. Martin says the graph should be translated right 3 units from the parent graph f(x) = x^2. Explain his error.

Martin is not correct. The graph should be translated left 3 units from parent graph.

Given :

The function

Martin says the graph should be translated right 3 units from the parent graph

we know that ,

, the graph will be translated 'a' units right

, the graph will be translated 'a' units left

From the given function g(x), 3 is added with x.

so, the graph of g(x) is translated 3 units left.

Martin is not correct. The graph should be translated left 3 units from parent graph.

Martin used (x + h)² instead of (x - h)²

Step-by-step explanation:

The vertex form of a quadratic equation is: y = a(x - h)² + k    where

f(x) = x²

g(x) = (x + 3)²

                ↓      

              h= -3

           Shifted LEFT 3 units
