The quadratic function f(x) has a vertex at (9,8) and opens upward. If g(x) = 4(x - 8)2 + 9, which statement is true? OA.
The maximum value of fx) is greater than the maximum value of g(x).
OB.
The maximum value of g() is greater than the maximum value of f(x).
Oc.
The minimum value of fx) is greater than the minimum value of g(x).
OD.
The minimum value of g(x) is greater than the minimum value of f(x).

the answer will be

i dont know men

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
