f(6) means that you look at x = 6 and notice the y-axis, then you will get the answer.
If you don't know. f(6) = -6 (Look at x = 6 then look at y = -6.)
Also for g(5), same with f(6). Look at x = 5 and notice the y-axis. When x = 5, y = -5.
Now we know that f(6) = -6 and g(5) = -5
Substitute f(6) = -6 and g(5) = -5 for easier look.
So the answer is 24.

Answer:
option 4 ⇒ 236 lb.
Step-by-step explanation:
Best explanation of the question is as shown in the attached figure.
we will use the parallelogram method to calculate resultant force.
to get the length of the resultant force ⇒ use the cosines law
The cosine law is a² = b² + c² - 2 * b * c * cos (∠A)
Applying at the question where b = F₁ , c = F₂ and ∠A = ∠x
Given that F₁ = 100 pounds , F₂ = 150 pounds and ∠x = 180° - 40° = 140°
∴ (Resultant force)² = 100² + 150² - 2 * 100 * 150 * cos (∠140) = 55481
∴ Resultant force = √55481 = 235.54 ≅ 236 pounds
The answer is option 4 ⇒ 236 lb.
