Answer: B) one
This one point is point U since it is on line segment CD. In contrast, a point like point E is not on line CD, so E is not collinear with C and D.
The equation of the piecewise function is 
<h3>The piecewise function</h3>
On the graph, we have:
- y = 3 for all x values not more than -1
- y = -1 for all values greater than 2
Hence, the piecewise function is:

<h3>The domain of the function</h3>
This is the set of input values
In (a), we have:
x ≤ -1 and x > 2
Hence, the domain is (∞, 3] u (2, ∞)
<h3>The range of the function</h3>
This is the set of output values
In (a), we have:
f(x) = 3 and f(x) -1
Hence, the range is [3] u (-1)

We have a system of equations in two variables, namely, a and c. Use the substitution to find a and c.
Answer:135
Step-by-step explanation:
bcs 45x60 is 2700 ÷20= 135
D. -1,-1 because If you were to place that on a graph you would get d. for your answer and you can also do it on a TI-83 plus calculator
