Answer 1

Answer:

For f(x - 3.5) the answer is that f(x) is translated 3.5 units right

You can figure that out by thinking that for x = 3.5 (which is 3.5 units to the right of x = 0, f(3.5 - 3.5) is the same that f(0), ... for x = 10.5 (which is 3.5 units to the right of x = 7, f(10.5 - 3.5) = f(7) ... and so for every value of x.

For 3.5 f(x) the answer is that f(x) is vertically stretched by a factor of 3.5 which you figure out from a table like this:

f(x)          3.5 f(x)

0               0

1               3.5

2                7

10             35

And from that you can see the 3.5 f(x) is horizontally compressed and vertically stretched respect to f(x).
