The functions f(x) and g(x) are described below.

f(x) = 32x + 8
g(x) = 32x - 9

The graph of g(x) is obtained by shifting down the graph of f(x) by _____ units.

But I'm not sure what the correct answer is.

anonymous · Answer

I think it's 1 but i'm not sure . . .

phi · Answer

both f(x) and g(x) are lines.
at x=0,  f(0)=8  and g(0)= -9
g(0) is 17 below f(0)
or -17 shift

anonymous · Answer

Oh so the answer is 17?

phi · Answer

yes.  f(x) shifted down by 17 will lie on top of g(x)

anonymous · Answer

Oh, thanks.

phi · Answer

notice if you start with 
f(x) = 32x + 8
and shift down by adding -17 
f(x) = 32x + 8 - 17
you get
32 x -9 
which matches g(x)
