Answer:
The values of y are 1 , 2 , 5 , 10 ⇒ answer B
Step-by-step explanation:
* We will use the substitution method to solve the problem
- The quadratic equation is y = x² + 4x + 5
- The values of x are -2 , -1 , 0 , 1
- We will substitute the values of x in the equation to find the
values of y
# At x = -2
∵ y = x² + 4x + 5
∵ x = -2
∴ y = (-2)² + 4(-2) + 5 = 4 - 8 + 5 = 1
∴ y = 1
# At x = -2
∵ y = x² + 4x + 5
∵ x = -1
∴ y = (-1)² + 4(-1) + 5 = 1 - 4 + 5 = 2
∴ y = 2
# At x = 0
∵ y = x² + 4x + 5
∵ x = 0
∴ y = (0)² + 4(0) + 5 = 0 + 0 + 5 = 5
∴ y = 5
# At x = 1
∵ y = x² + 4x + 5
∵ x = 1
∴ y = (1)² + 4(1) + 5 = 1 + 4 + 5 = 10
∴ y = 10
* The values of y are 1 , 2 , 5 , 10 ⇒ from left to right

Answer:
A) Domain =
B) Range =
Step-by-step explanation:
Domain is the number of people and Range is the amount of money they make.
A)
Since seating capacity is at max 63,026, and minimum people to attend would be 0. Hence the domain is between 0 and 63,026
We can say:
Domain =
B)
The tickets cost 30 each and if there are no people in attendance, they raise $0. And if the stadium is full, they can raise:
63,026 * 30 = 1,890,780
Hence, the range would be minimum $0 and maximum $1,890.780
We can say:
Range =
