Assume that f is a one-to-one function. (a) if f(1) = 12, what is f −1(12)

As it is one-to-one function, f −1(12) = 1

6 0

F-1(x) is the inverse of f(x)

The domain of f(x) = range of f(-1)x and vice-versa.

So f-1(12) = 1.

First you need to add the prices to get 85.55. Then 100 - 85.55 is 14.45.

She will have $14.45 leftover

$\dfrac{(x-2)^2}{49}+\dfrac{(y+5)^2}{36}=1$

The equation of a elipse:

$\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1$

The length of the major axis is equal 2a if a > b or 2b if b > a.

We have

$a^2=49\to a=\sqrt{49}=7\\\\b^2=36\to b=\sqrt{36}=6\\\\a > b$

therefore the length of the major axis is equal 2 · 7 = 14.
