Given that f(x)=8x^3-22x^2-4 and g(x)=4x-3

Question says to find f of x over g of x which simply means divide value of f(x) by value of g(x)

Dividing them gives:

\frac{f(x)}{g(x)}=\frac{8x^3-22x^2-4}{4x-3}

Denominator is already in factored form which can't divide numerator means it can't be simplified more.

Hence final answer is \frac{f(x)}{g(x)}=\frac{8x^3-22x^2-4}{4x-3}.

other part of question is not clear so i will skip them.

Answer:

The correct answer is the first one.

Step-by-step explanation:

We have the functions f(x) = 8x^3-22x^2-4 and g(x) = 4x-3. Then, the fraction is

\frac{f(x)}{g(x)} = \frac{8x^3-22x^2-4}{4x-3}.

If we want to give a ‘‘simplified’’ expression for this quotient we must do a a division of polynomials. The algorithm is the analogue for the division of integers. Attached there is an image of the procedure.

After the completion of the division algorithm we obtain

\frac{f(x)}{g(x)} = \frac{(4x-3)(2x^2-4x-3)-13}{4x-3} = 2x^2-4x-3 - \frac{13}{4x-3}.

Joshua is trying to decide if there is a relationship between a driver's age and the number of traffic tickets they get he surve
Rashid [163]

Hello!


The number of tickets is dependent on age, so age is the independent variable.


Think of it as a y = mx equation. In this equation, x is the input, and y changes depending on the value of x inputted.


In this situation, y is the number of tickets, as y changes depending on the age x inputted. x is age, the independent variable.
