Function represents a relationship between variables. The product of the two given functions (k·p)(x) is 2x³-8x²-7x+28.
<h3>What is Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
Given to us
k(x) = 2x² − 7
p(x) = x − 4
As the two equations are given to us, k(x) and p(x), and we need to find (k ∘ p)(x), And we know the product of two functions can be written as,

therefore,

Hence, the product of the two given functions (k·p)(x) is 2x³-8x²-7x+28.

Answer:
$7.50
Step-by-step explanation:
We have the following data:
Margin of Error = E = 2.7 % = 0.027
Sample size = n = 900
Proportion of adults in favor = p = 60% = 0.6
We need to find the confidence level. For this first we need to find the z value.
The margin of error for a population proportion is given as:

Using the values, we get:
As, seen from the z table, z=1.65 corresponds to the confidence level 90%. So, the answer to this question is option B
