Answer:
3 : 1 : 2
Step-by-step explanation:

Answer:
See below
Step-by-step explanation:
<h3>Part (a)</h3>
f(x - 1) is the translation of f(x) one unit right.
So the graph is exactly same shape but shifted right one unit.
<h3>Part (b)</h3>
f(x) has vertex (-1, 2)
<u>The function y = f(-x) + 2 will have the vertex changed as per rule:</u>
<u>So the new vertex is:</u>
- (-1, 2) → (-(-1), 2 + 2) = (1, 4)
2: (360-50-50)/2=130 degrees
The amount of stress which is kind of confusing so therefore i would go with psi even though stress would also be an option.
