From the attached graph, we see that
f(x) is increassing in (- ∞ , -4), and
f(x) is decreasing in ( -4, ∞ )
therefore
The function is increasing for all real values of x where x < –4. TRUE
<span>The function is increasing for all real values of x where –6 < x < –2. (FALSE, f(x) is positive in this range)
</span><span>The function is decreasing for all real values of x where x < –6 and where x > –2. (FALSE, f(x) is negative in this range)
</span><span>The function is decreasing for all real values of x where x < –4. (FALSE, f(x) is decreasing ∀ x>-4</span>
Answer:
40° or 2π/9 rad
Step-by-step explanation:
Let f(x) = 0 and solve
2cos (3x) + 1 = 0
2cos (3x) = -1
cos (3x) = -1/2
3x = arccos (-1/2) = 120
x = 40° or 2π/9 rad
Your adding 5 every time :)
