Answer:

3

Step-by-step explanation:

The points they have in bold is probably a hint to the problem.

The points they have in bold are (1,2) on curve g which means g(1)=2

and (3,2) on curve f which means f(3)=2.

g(x)=f(kx)

We know g(1)=2 so if we replace the x's with 1, we get:

g(1)=f(k*1)

g(1)=f(k)

2=f(k).

Now we just need to solve f(k)=2 for k.

We know the point (3,2) is on f so f(3)=2.

If you compare:

f(k)=2

and

f(3)=2

then you should see that k=3.
