Answer:

x f(x)

–3 –12

–1 –4

4 16

Step-by-step explanation:

Let us find the each function by evaluating them one by one

1.

x f(x)

–3 –12  = -3 x 4

–1 –4  = -1 x 4

4 16 = 4 x 4

By observing the data we can see that

f(x) = 4x

2.

x f(x)

–2 6  = -2 x -3

–1 3  = -1 x -3

1     –3= 1 x -3

f(x) = -3x

3.

x f(x)

1 0.25  = 1/4

8 2  = 8/4

16 4 = 16/4

f(x)= x/4

4.

x f(x)

–9 3  = -9/-3

–3 1  = -3/-3

21 –7  = 21/-3

f(x) = x/-3

Hence comparing all the four function with our given function f(x)=3x , we see that f(x) =4x has a greater rate of change that f(x)=3x
