F(x)=x^2-8x+12 in vertex form

vertex form f(x) =  (x - 4)^2  - 4

Step-by-step explanation:

f(x)=x^2-8x+12 in vertex form

look at   -8x

take -8  divide it by 2  and square result   get   16

f(x) = x^2   - 8x  + 16  -  16  + 12

f(x) =  (x - 4)^2  - 16  + 12

f(x) =  (x - 4)^2  - 4

vertex form f(x) =  (x - 4)^2  - 4

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
