Which function shows a fabric with a price of $1.25 per square yard?

We are given price per square yard of a fabric  = $1.25.

Let us assume total number of square yard of the fabric = x square yards.

And let us assume function f(x) is given by Total price of the fabric.

Total price of the fabric = Price per square yard of a fabric × total number of square yard of the fabric.

We took total number of square yard of the fabric by a variable x and price per square yard of a fabric is $1.25.

Plugging values in above statement, we get

f(x) = 1.25 × x

f(x) = 1.25x.

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
