Answer:
It is not a one to one function

Determine if f(x) = round(x) is a one to one function
This question is best answered using illustrating values;
Let x = 1.1
f(x) = round(x) becomes
f(1.1) = round(1.1)
f(1.1) = 1
Let x = 1.3
f(x) = round(x) becomes
f(1.3) = round(1.3)
f(1.3) = 1
Notice that for the two values of x, f(x) has the same value of 1.
This two illustrating values can be used to conclude that the fuction is not one-to-one.
Answer:
1. D. ray PS
2. C. angle GFE
3. A. 30 deg
Step-by-step explanation:
1. To name a ray, use two points on the ray. The first point must be the endpoint. The second point can be any point on the ray.
ray PS and ray PT are both correct.
Choose D. ray PS
2. Two ways of naming an angle are: 1. Use just the vertex point. 2. Use three points: a point on one ray, the vertex, a point on the other ray in that order.
This angle can be named:
angle EFG
angle GFE
angle F
Choose C. angle GFE
3. Angles CBE and ABD are vertical angles. Vertical angles are congruent. They have the same measure. Since angle ABD measures 30 deg, then angle CBE also measures 30 deg.
Choose: A. 30 deg
