Use f(x) = 1/2 x and f -1(x) = 2x to solve the problems. f(2) = 1 f−1(1) = 2 f−1(f(2)) = 2 f−1(−2) = f(−4) = f(f−1(−2)) =
vampirchik [111]

Answer:

In this problem, we are given the following functions:

f(x)=\frac{1}{2}x

and its inverse function:

f^{-1}(x)=2x

First of all, we want to calculate f(2). This can be obtained by substituting

x = 2

into f(x). Doing so, we find:

f(2)=\frac{1}{2}\cdot 2 = 1

Then we want to calculate f^{-1}(1). We can do it by substituting

x = 1

into f^{-1}(x). Doing so,

f^{-1}(1)=2\cdot 1 = 2

Then we want to calculate f^{-1}(f(2)), which can be found by calculating f(2) and then using it as input for f^{-1}(x). We know that

f(2) = 1

Therefore,

f^{-1}(f(2))=f^{-1}(1)=2

Then we want to calculate f^{-1}(-2), which can be calculated by plugging

x = -2

into f^{-1}(x). Doing so,

f^{-1}(-2)=2\cdot (-2)=-4

Then we want to calculate f(-4); by substituting

x = 4

into f(x), we find

f(-4)=\frac{1}{2}\cdot (-4)=-2

Finally, we want to find f(f^{-1}(-2))

We know already that

f^{-1}(-2)=-4

So we have:

f(f^{-1}(-2))=f(-4)=-2

It seems logical that restaurant chains with more units (restaurants) would have greater sales. Ca 5 n we predict sales by measu
svetoff [14.1K]

Answer:

Step-by-step explanation:

Hello!

A regression model was estimated in order to test if the number of units of a restaurant chain affecta the sales of said restaurant chains.

The estimated model is:

Y= a + bX

Where

Y: is the sales of a restaurant chain

X: number of units of a restaurant chain

Looking at the computed data, the estimated coefficients are:

a= 4.633131413

b= 0.439724072

The correct regression equation to predict Sales based on Units, according to this analysis, is..

Y= 4.63 + 0.44X

I hope it helps!
