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\\&#10;f^{-1}(-1)=0.5^{-1}\\&#10;f^{-1}(-1)=2

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

f^{-1}(x)=0.5^x\\&#10;f^{-1}(0)=0.5^0\\&#10;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.
