Answer:
Step-by-step explanation:
The domain is {-1, 2} (the domain has only two values).
The range is {-4, -3, 2} (the range contains three values)

Answer:
C. y = x - 4
Step-by-step explanation:
A.
y = x + 4
-1 = 3 + 4
-1 = 7
B.
y = -3x
-1 = -3(3)
-1 = -9
C.
y = x - 4
-1 = 3 - 4
-1 = -1
D.
y = 3x
-1 = 3(3)
-1 = 9
The domain x ∈ {-5; 0; 5}
the relation: 2x + y + =1 → y = 1 - 2x
Put the values of x from domain to the equation of the relation:
for x = -5 → y = 1 - 2(-5) = 1 + 10 = 11for x = 0 → y = 1 - 2(0) = 1 - 0 = 1for x = 5 → y = 1 - 2(5) = 1 - 10 = -9
Answer: {-9; 1; 11}
Answer:
Profit P(x) = 53x-12 and On selling 20 video games profit will be 1048.
Step-by-step explanation:
In the given question functions are Revenue function : R(x) = 60x and Cost function : C(x) = 12+7x for the sale of x video games
As we know profit = sale price - cost price
Therefore P(x) = R(x) - C(x)
Or P(x) = (R-C)x = 60x - (12+7x)
P(x) = 60x -12 - 7x
P(x) = 53x -12
Now the profit on selling 20 video games will be
P(20) = 53×20 -12 = 1060 -12 = 1048.
