Functions Question
The figures above show the graphs of the functions around f and g. The function f is defined by
f(x)=2x^3+5x^2x
The function g is defined by
g(x)=f(xh)k, where h and k are constants.
What is the value of hk?
I don't know how to get the graph onto the internet but here are the details:
y=f(x) has points:
(3,6)
(1,6)
y=g(x) has points:
(4,5)
(0,5)
The answer to this q says:
The second graph moves down 1 and to the left 1. Remember that when a graph moves to the left it is represented as (x+h)  the same as x(1). So h=1. Because a negative k represents moving down, k=1.1*(1)=1.
I'm really really confused about the answer. First of all, where did the "1.1" come from?? And second of isn't it h multiplied by k? Therefore if h=1 and k=1, then 1*1 = (positive) 1  though the answer is 1.
