Answer:
![f(x - 4) = x^2 - 6x+ 8](https://tex.z-dn.net/?f=f%28x%20-%204%29%20%3D%20x%5E2%20-%206x%2B%208)
Step-by-step explanation:
Given
![f(x) = x^2 + 2x](https://tex.z-dn.net/?f=f%28x%29%20%3D%20x%5E2%20%2B%202x)
Required
Find f(x - 4)
Substitute x - 4 for x
![f(x - 4) = (x- 4)^2 + 2(x - 4)](https://tex.z-dn.net/?f=f%28x%20-%204%29%20%3D%20%28x-%204%29%5E2%20%2B%202%28x%20-%204%29)
Expand
![f(x - 4) = x^2 - 8x + 16 + 2x - 8](https://tex.z-dn.net/?f=f%28x%20-%204%29%20%3D%20x%5E2%20-%208x%20%2B%2016%20%2B%202x%20-%208)
Collect like terms
![f(x - 4) = x^2 - 8x + 2x+ 16 - 8](https://tex.z-dn.net/?f=f%28x%20-%204%29%20%3D%20x%5E2%20-%208x%20%2B%202x%2B%2016%20%20-%208)
![f(x - 4) = x^2 - 6x+ 8](https://tex.z-dn.net/?f=f%28x%20-%204%29%20%3D%20x%5E2%20-%206x%2B%208)
Answer:
let c is a point between a and b we can find the coordinates of c by using mid-point formula
the coordinate x of c is equal to
x=(x1+x2)÷2
x=(3+27)÷2
x=30÷2
x=15
the coordinate y of c is equal to
y=(y1+y2)÷2
y=(2+30)÷2
y=32÷2
y=16
so the coordinates of c are (15,16)
