The figures above show the graphs of the functions around f and g. The function f is defined by

f(x)=2x^3+5x^2-x

The function g is defined by

g(x)=f(x-h)-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.
