A
(X-7)(x-4) -> x^2 -11x + 28
Multiply that by the 2 and you get the original equation!
So a diver went 25.65 ft BELOW so it's negative.
then he went 16.5 ft further down, so that's negative also.
he then rose 12.45 ft, so that's positive.
so the expression is: -25.65+-16.5+12.45, the answer is 23.7
Answer:
f(1) = -6
Explanation:
When you look at the points with x = 1, you will see a point that is open (o) and closed (•) The point that is closed (the one you are looking for) is an actual point of the function. The open point is where the function is discontinuous.
The answer for your question is x=-1
