Answer:
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

Answer:
d
Step-by-step explanation:
Let m = number of miles.
Each mile costs $2.35, so m miles cost 2.35m.
The flat fee is $2.
The total cost is
2.35m + 2
He can spend no more than $47, so he can spend $47 or less,
2.35m + 2 <= 47
Answer: d
