When ( y = f(2x) ), the domain is halved. When ( y = \sqrt-x ), domain becomes ( x \le 0 ). Always check domain in DSE long questions.
The most common mistake in DSE exams is horizontal translation and scaling. transformation of graph dse exercise
, what are the coordinates of the new vertex on the graph of Step 1: Identify Horizontal Change Inside the brackets, we see . In DSE math, changes inside the bracket affecting When ( y = f(2x) ), the domain is halved
The graph of ( y = 2^x ) is reflected in the line ( y = x ), then stretched vertically by factor 3, then translated 2 units down. Find the equation of the resulting curve. When ( y = f(2x) )
