The function f(x) = x2 has been translated 9 units up and 4 units to the right to form the function g(x). Which represents g(x)?
For this case, the parent function is given by:
\(f (x) = x ^ 2
\)
We apply the following transformations:
Vertical translations:
Suppose that k> 0
To graph y = f (x) + k, move the graph of k units upwards:
For k = 9 we have:
\(h (x) = x ^ 2 + 9
\)
Horizontal translations:
Suppose that h> 0
To graph y = f (x-h), move the graph of h units to the right
For h = 4 we have:
\(g (x) = (x-4) ^ 2 + 9
\)
Answer:
The function g (x) is given by:
\(g (x) = (x-4) ^ 2 + 9\)
