You see that

[tex] f(-2)=8=2\cdot 4=2 g(-2),\\ f(-1)=6=2\cdot 3=2 g(-1),\\ f(0)=8=2\cdot 4=2 g(0),\\ f(1)=14=2\cdot 7=2 g(1) [/tex].

This rule gives you an oportunity to state that [tex] f(x)=2g(x) [/tex]. Therefore, [tex] g(x)=\dfrac{1}{2} f(x) [/tex]. Multiplying function f(x) by factor 1/2 you obtain function g(x) that is compression function f(x) in the y-direction.

Answer: compression function f(x) in the y-direction by factor 1/2.

Answer:

Vertical Compression

Step-by-step explanation:

If y = f(x), then y = a×f(x) gives a vertical stretch when a > 1 and a vertical compression when 0 < a < 1.

For this question, each new point is 1/2 of the old point, meaning that a is 1/2.

Since 1/2 is a and 0 < a < 1, the transformation that occurred on the function f to get function g is a vertical compression.
