Step-by-step explanation:
b
The function can be expressed as a rational function is
.
We have to determine
Which of the following is written as a rational function?
According to the question
A rational function is a function that can be expressed as the quotient or ratio of two polynomial functions, where the polynomial in the denominator must have a degree of at least 1.
A rational function can be expressed as;

Then,
The required rational function is expressed as;

Where p(x) is (x-5) and g(x) is 3x.
Therefore,
The function is,

Hence, the function can be expressed as a rational function is
.

I hope this helps! I would check with someone else first though.
i can not give the answer unless you still cannot find it after these steps but I have steps that might help
1. Set the matrix (must be square).
2. Reduce this matrix to row echelon form using elementary row operations so that all the elements below diagonal are zero.
3. Multiply the main diagonal elements of the matrix - determinant is calculated.
