We have the following function: f (x) = 4x ^ 2 - 16 Horizontal translations Suppose that h> 0 To graph y = f (x-h), move the graph of h units to the right. We have then: f (x) = 4 (x-5) ^ 2 - 16 Then, Vertical translations Suppose that k> 0 To graph y = f (x) -k, move the graph of k units down. We have then: f (x) = 4 (x-5) ^ 2 - 16 - 2 f (x) = 4 (x-5) ^ 2 - 18 Answer: f (x) = 4 (x-5) ^ 2 - 18 option C
