To find the inverse,
First, you would have to switch the domain and range. In other words, swap x and y:
h(x) = 3/ -x-2
y = 3/ -x-2
x = 3/ -y-2
Then, when you have this, simply solve for y:
x = 3/-y-2
x (-y-2) = 3/-y-2 (-y-2)
x(-y-2) /x= 3 /x
-y-2 = 3/x
-y = 3/x + 2
y = -3/x -2
So the inverse would be
h⁻¹(x)= -3/x -2
Answer:
$38.42
Step-by-step explanation:
Answer:
(D) 20%
Step-by-step explanation:
The original price of the two items = $60 + $40 = $100
The discounted price of the two items = $60 + ($40 x 0.5) = $60 + $20 = $80
To find the percent discount he received off his total purchase, we need to divide the difference between the original price and the discounted price by the original price.
$100 - $80 = $20
$20 ÷ $100 = 0.2
0.2 = 20%

Answer: B) x ≥ -2
<u>Step-by-step explanation:</u>
Domain represents all of the x-values.
In the given graph, the x-values start at -2 and go continuously through to positive infinity.
Therefore, x ≥ -2
