We have the following functions:
f (x) = x + 2
g (x) = 1 / x + 2
Multiplying we have:
(f * g) (x) = (x + 2) * (1 / x + 2)
Rewriting:
(f * g) (x) = (x + 2 / x + 2)
(f * g) (x) = 1
Therefore, the domain of the function is any real number.
Answer:
a. all real numbers
The association between the given lines is that they are 'neither perpendicular nor parallel.'
To prove, let's convert the given equations in their slope-intercept form i.e. 'y = mx + b'
-7x + 2y = 3
2y = 7x + 3
y = 7/2x + 3/2
-6x + 3y = 2
3y = 6x + 2
y = 2x + 2/3
This shows that both the lines have different slopes, as well as, intercepts of y. And,
= 2 * 7/2 ≠ -1
Thus, it is not perpendicular also.
Therefore, <u>option D</u> i.e. 'neither perpendicular nor parallel' is the correct answer.
