Now, I have answered this question and it seems very simple. But the answer they give is different to mine, and i graphed to check, and it seems I am correct, but I want you guys to tell me what you think. Part
c) is what I'm concerned with.
a) The graph of g is obtained from the graph of the function f with rule
by a translation by +3 units parallel to the x-axis. Write down the rule for g.
Now, i wrote
which is correct.
b) The graph of h is obtained from the graph of g by a translation by −1 unit parallel to the y-axis. Write down the rule for h.
I wrote
c) The graph of k is obtained from the graph of h by a dilation by a scale factor of 0.5 from the y-axis. Write down the rule for k.
I wrote
, but they say:
. Now, how can that be correct since their version changes the turning point completely? It's basically a totally different graph, isn't it?
So tell me what you think.
