What transformation was not done to the linear parent function, f(x)=x, to get the function g(x)=-3(x-4)-7 a. reflection over the x-axis b. shift down 7 units c. shift right 4 units d. horizontal stretch by a factor of 3

D. Horizontal stretch by a factor of 3.

Step-by-step explanation:

Below are some transformations for a function :

If , then it is shifted "k" units down.

If , then it is shifted rigth"k" units.

If , then it is reflected across the x-axis.

If and , then it is stretched vertically by a factor of "c".

If and , then it is stretched horizontally by a factor of .

Based on this, the transformations done to the function  to get the function are:

- It is shifted 7 units down.

- It is shifted rigth 4 units.

- It is reflected over the x-axis.

- It is vertically stretched by a factor of 3.

Therefore, the transformations that was not done to the function  to get the function is:

Horizontal stretch by a factor of 3.

0, additive identity.

Step-by-step explanation:

6 + x = 6

x = 6 - 6

x = 0
