B. {0, 3, 5, 8}

2. IS the following relation a function {(0.3,0.6),(0.4,0.8),(0.3,0.7),(0,5,0.5)}

B. No

3. Use the vertical line test to determine whether the relation graphed below is a function.

A.Yes

4. Sound travels about 343 meters per second.the function d(t)=343t gives the distance d(t) in meters that sound travels in t seconds. How far does sound travel in 8 seconds?

C.2,744 meters

5. What is the value of the range of the function f(x)=x^2+2 for the domain value 1/4?

D. Y = 2 1/16

I Hope THIS HELPS

Answer 2

The domain is the x-values. Therefore making B {0,3,5,8} the right answer. Hope that this helped!
