Answer 1

answers b and c are identical ? Is one g(x) = -14x ?

Answer 2

If f is a function and k is a constant, then the graph of y = k *f(x) is the graph of y = f(x) vertically compressed by a factor of k if 0 < k < 1

In this case, k = 1/7, therefore,

y = 1/7*2x = 2/7(x)

Answer 3

imho, "compress by" a fraction is always confusing.... compress implies "make smaller". So "make smaller by a factor of x" could easily mean "divide by x"

But @Hero is probably on the right track here...

Answer 4

Actually, it is reflected about the x-axis so it's -2/7x

Answer 5

What happens to points in the "positive x,y" quadrant (the upper right) when you reflect them across the x-axis? Which quadrant do they end up in?

Answer 6

ok thx guys
