The use of the symbol • in <span>(p•q)(x)
is confusing.
You may be using it to indicate multiplication or to indicate composition of functions.
The operation and the results will be different in each case.
So, make sure that you interpret the problem correctly. I will do the problem for the two cases to help you.
1) if </span><span>• means multiplication:
</span>use the distributive property:
<span>(p•q)(x)
= (2x^2 - 4x) (x - 3) = 2x^3 - 6x^2 - 4x^2 + 12 x = 2x^3 - 10x^2 + 12x
2) if </span><span>• means compositon of functions:
=> </span><span>(p•q)(x)
= p [ q(x)] = p [ x -3] = 2 (x - 3)^2 - 4(x - 3)
= 2[x^2 - 6x + 9] - 4x + 12 = 2x^2 - 12x + 18 - 4x + 12 = 2x^2 - 16x + 30
Then, only make sure of the use of the symbol </span><span>• in (</span><span>p•q)(x)
, which you can find in the context of the question.</span>

Answer:
Step-by-step explanation:
From the answer choices available the answer that is correct is that for day-to-day business data analysis, most firms rely on a large staff of expert statisticians. This is because on a daily basis firms receive large sets of data from all of their business movements, therefore a large staff of highly experienced individuals is needed in order to handle and document all of these numbers carefully so that no mistakes are made. The smallest mistake in the firm's financial accounts can lead to a very costly loss for the company.
