= (0.3)(-9.2)(-8.1)(4.2)(-0.8) \\ = (-2.76)(-8.1)(4.2)(-0.8) \\ = (22.356)(4.2)(-0.8) \\ = (93.8952)(-0.8) \\ = -75.11616

So, yeah the product is Nagative.

The simplest way is to count the number of NEGATIVE SIGNS in the problem before doing any multiplying If there are an ODD number of NEGATIVE TERMS the answer is NEGATIVE if an EVEN NUMBER the answer is POSITIVE In this problem there are 3 negative terms, so the answer is NEGATIVE after knowing the sign, just multiply the numbers without worrying about the sign, you already know it

Question 1<br> Let f(x) = 2x^2 - 3x - 4 and g(x) = x + 5. Find (fg)(x).
Scilla [17]

The function (fg)(x) is a composite function

The value of the function (fg)(x) is 2x^3 + 7x^2 - 19x - 20

<h3>How to determine the function (fg)(x)?</h3>

The functions are given as:

f(x) = 2x^2 - 3x - 4 and g(x) = x + 5.

To calculate (fg)(x), we make use of

(fg)(x) = f(x) * g(x)

So, we  have:

(fg)(x) = (2x^2 - 3x - 4) * (x + 5)

Expand

(fg)(x) = 2x^3 - 3x^2 - 4x + 10x^2 - 15x - 20

Collect like terms

(fg)(x) = 2x^3 - 3x^2 + 10x^2 - 4x - 15x - 20

Evaluate

(fg)(x) = 2x^3 + 7x^2 - 19x - 20

Hence, the function (fg)(x) is 2x^3 + 7x^2 - 19x - 20
