It would be the middle choice. The choice on the left represents a line, and the choice on the right represents a line segment.
Hope this helps!
Answer:

Step-by-step explanation:
We have the two functions:

And we wish to find:

First, let’s find f(2) first. So, we will substitute 2 for x for f(x):

Hence, we can now substitute 3 for f(2):

Now, we can find g(6). Substitute 6 for t for g(t):

Therefore:

Answer:
$148.75
Step-by-step explanation:
$175 · 15% = $26.25
$175 - $26.25 = $148.75
Answer:
The y-value (output) is equal to 1
Step-by-step explanation:
f(x) = 1
f(x) takes the place of y, so this could be rewritten as
y = 1
Answer:x=150
Step-by-step explanation:
Step 1: Subtract 1.2x from both sides.
0.8x+20−1.2x=1.2x−40−1.2x
−0.4x+20=−40
Step 2: Subtract 20 from both sides.
−0.4x+20−20=−40−20
−0.4x=−60
Step 3: Divide both sides by -0.4.
−0.4x
−0.4
=
−60
−0.4
