The product of P(x) = 9x and R(x) = 9x - 4 is found by multiplying the two functions, resulting in 81x^2 - 36x.
Step-by-step explanation:
To find the product of the functions P(x) and R(x), we need to multiply them together. Given P(x) = 9x and R(x) = 9x - 4, the product P(x)*R(x) is calculated as follows:
Multiply P(x) by R(x): (9x) * (9x - 4)
Distribute 9x across the terms in R(x): 9x * 9x - 9x * 4
Calculate each term: 81x2 - 36x
So, the product of P(x) and R(x) is 81x2 - 36x.
