Could someone please help me with this question:
The figure on the right shows the graph of y = f(x) = -x.
Use the graph to sketch the graph of each of the following functions. Mark on each sketched graph the new position and coordinates of the point (2,-2).
(a) y = f(x + 4) + 3
(b) y = 2f(x) + 3
The answers to (a) and (b) are given as the two pioints (-2,1) and (2,-1) respectively.
I get stuck with the tropic of quadratic equation transformations, particularly about using a given graph to sketch a graph.
I appreciate your help. Thanks in advance.
