Answer:
Domain: -∞≤x≤∞
Range: 0≤F(x)≤∞
Step-by-step explanation:
The x variable can take any value.
In the case of F(x), the function only can take positive values, due to the absolute value function, and the function does not have any other restriction.
Answer:
I suggest you convert them to improper fractions. Find a common denominator and change back to mixed number.
Step-by-step explanation:
Answer:
(B) π/12 + π/6 k
Step-by-step explanation:
Points of inflection are where f"(x) = 0 and changes signs.
f(x) = cos²(3x)
f(x) = (cos(3x))²
f'(x) = 2 (cos(3x))¹ × -sin(3x) × 3
f'(x) = -6 sin(3x) cos(3x)
Using double angle formula:
f'(x) = -3 sin(6x)
f"(x) = -3 cos(6x) × 6
f"(x) = -18 cos(6x)
0 = -18 cos(6x)
0 = cos(6x)
6x = π/2 + 2πk or 6x = 3π/2 + 2πk
We can simplify this to:
6x = π/2 + πk
x = π/12 + π/6 k
Answer:
n=-4
Step-by-step explanation:
-6n-(-2n)=16
-6n+2n=16
-4n=16
n=16/-4
n=-4
