Comparing the functions, from the tables, it is found that (f - g)(x) is positive in the interval (–∞, 9)
.
----------------------
- For the subtraction function, we simply subtract both functions, thus:
- It is positive if f is greater than g, that is: f(x) > g(x).
- It is a linear function, so one function is greater before the equality, one after.
- They are equal at x = 9.
- If x < 9, f(x) > g(x), and thus, (f - g)(x) is positive, which means that the desired interval is:
(–∞, 9)

Answer: 
Step-by-step explanation:
Assuming the described expression is:
And knowing the condition 
and 
We cansimplify it following the rules related to the exponents with the same base:
Finally:
We are given the inequality x < -2 or x ≥ 3 in which the problem asks to determine the domain of the inequality. In this case, this means numbers less than -2 or numbers equal to 3 and greater than three. The relation that illustrates the previous statement is B. x e(-∞,-2) n[3,∞)
Both these graphs will pass through the origin so you need to work out the difference in areas by integrating
INtegral k cos x (between the limits 0 and a) - Intgral kx^2 ( between 0 and a) = 2
Find k
(where a is the value of x on positive side of the graph where the 2 curves intersect)
