Answer:

Yes

Step-by-step explanation:

Draw vertical lines parallel to the "y" axis and you will notice that they only cross the graph once. This only happens in function graphs.

Hope this helps

Answer:

The graph represents a function

Step-by-step explanation:

As you can observe, there is only one unique output assigned to every input. If an input contained 2 or more outputs, the relationship wouldn't be a function.

HELP asap AB=85m Find the length of Line CD

Aleks [24]

CD = x
BC = y
AB = 85
BD = BC+CD = y+x

tan(angle) = opposite/adjacent
tan(28) = BC/AB
tan(28) = y/85
85*tan(28) = y
y = 85*tan(28)
y = 45.1953016912257

tan(angle) = opposite/adjacent
tan(31) = BD/AB
tan(31) = (y+x)/85
tan(31) = (45.1953016912257+x)/85
85*tan(31) = 45.1953016912257+x
51.0731526173427 = 45.1953016912257+x
51.0731526173427-45.1953016912257 = 45.1953016912257+x-45.1953016912257
5.877850926117 = x
x = 5.877850926117

So CD is roughly 5.877850926117 meters
