An inverse function is a function that reverses another function, so we have a function called:

Then, the inverse function will be as follows:

Given that

, we need to isolate x in terms of y:

∴

So:

and

therefore, exchanging variables x and y:

and


and

Which are the figures shown below.
Answer:
Option C (f(x) =
)
Step-by-step explanation:
In this question, the first step is to write the general form of the quadratic equation, which is f(x) =
, where a, b, and c are the arbitrary constants. There are certain characteristics of the values of a, b, and c which determine the nature of the function. If a is a positive coefficient (i.e. if a>0), then the quadratic function is a minimizing function. On the other hand, a is negative (i.e. if a<0), then the quadratic function is a maximizing function. Since the latter condition is required, therefore, the first option (f(x) =
) and the last option (f(x) =
) are incorrect. The features of the values of b are irrelevant in this question, so that will not be discussed here. The value of c is actually the y-intercept of the quadratic equation. Since the y-intercept is 4, the correct choice for this question will be Option C (f(x) =
). In short, Option C fulfills both the criteria of the function which has a maximum and a y-intercept of 4!!!
Answer:
6 mins, and the altitude will be 16,800 ft
Step-by-step explanation:
1st: Subtract 3000 from 34800
2nd: Multiply 2 to 2800
Keep doing this until you get the same altitude for each one.
