Question

Using the graph of f(x) and g(x), where g(x) = f(k⋅x), determine the value of k.
−2
negative one half
one half
2

Answer 1

I think it is 1 am I right?

Answer 2

this is a little hard to explain, but notice how the g(x) graph is being compressed horizontally so that the new slope is 2* the old slope

Answer 3

so the answer is 2? or -2?

Answer 4

negative stretch factor would imply a reflection across the x-axis which is not present here

so the solution is positive 2

Answer 5

*reflection across y but you get the idea

Answer 6

ohh got it, thanks
