Find f(x) if it is known that f(2a−1)=7a−13.

The required function f(x) is expressed as f(x)=3.5x-87.5

Given the function f(2a−1)=7a−13

To get f(x), we will equate x with 2a - 1 to find the value of x

x = 2a - 1

x + 1 = 2a

a = (x + 1)/2

Substitute a = (x + 1)/2 into the function as showb:

Hence the required function f(x) is expressed as f(x)=3.5x-87.5

Step-by-step explanation:

Given:

The given function in terms of 'a' is given as:

In order to determine , we need to make equal to 'x' and find the value of 'a'. Therefore,

Now, plug in the value of 'a' on both sides, we get:

Therefore, the expression for the function in terms of 'x' is:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
