Compare the graphs of y = x and y = 2x. How are they related?a. The graph of y = 2x represents a transformation of the parent function, y = x, which makes the graph twice as steep.b. The graph of y = 2x represents a transformation of the parent function, y = x, which makes the graph half as steep.c. The graph of y = x represents a transformation of the parent function, y = 2x, which makes the graph half as steep.d. The graph of y = x represents a transformation of the parent function, y = 2x, which makes the graph twice as steep.
