Answer/Step-by-step explanation:

1. -14

2. 3

3. -3

4. 10

5. -8

1. 4 x -3 = -12 - 2 = 14

2. -3 x 2 = -6 + 9 = 3

3. 8 divided by 4 = 2 - 5 = -3

4. 3/2 = 1.5 x 2 = 3 + 7 = 10

5. -9/3 = -3 - 5 = -8

The inverse of the logarithmic function f(x) = log0. 5x is f−1(x) = 0. 5x. What values of a, b, and c complete the table for the

Elan Coil [88]

The value of a, b and c can be calculated using the inverse function.

The calculated the value of a= 2, b=1 and c= -2.

Given:

The function is $f(x)=\log_{0.5}x$ and its inverse is $f^{-1}(x)=0.5^x$ .

<h3>What is an inverse function?</h3>

The inverse function of a function is defined if $f$ is a function that undoes the operation of $f$ .

The inverse of $f$ exists if and only if $f$ is bijective, and if it exists, is denoted by $f^{-1}$ .

Substitute the value of x= -1 in a given inverse function and calculate the value of a.

$f^{-1}(x)=0.5^x\\
f^{-1}(-1)=0.5^{-1}\\
f^{-1}(-1)=2$

Substitute the value of x is 0 in given inverse function.

$f^{-1}(x)=0.5^x\\
f^{-1}(0)=0.5^0\\
f^{-1}(0)=1$

Substitute the value of x is 2 in given inverse function.

$f^{-1}(x)=0.5^x\\f^{-1}(2)=0.5^2\\f^{-1}(2)=-2$

Therefore, the value of a= 2, b=1 and c=-2.
