So, 30% is 0.30, but since you are taking off 30%, you are going to have 70% of the price which is 0.70. The word "of" lets you know that you are going to multiply. So, what you do is 150•0.70=105. The discounted price is $105
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)

Answer:
{8,-4,-10}
Step-by-step explanation:
re arrange relation, im going to assume x is the domain input and y is the range.
-3x+2=y
plug in every element of the set x to get the range set y
-3(-2)+2=y
y=8
-3(2)+2=y
y=-4
-3(4)+2=y
y=-10
so the range is {8,-4,-10}
