Answer:
B. 1 horse per 20 pounds hay
C. YEs, an equation that can represent this is y=20x where x is the number of horses and y is the hay. Because i can make an equation that works for any value in this table, it is proportional.
Step-by-step explanation:
Answer:
a) Function
b) Not a function
c) Function
d) Not a function
Step-by-step explanation:
a) Domain = { 7,-6,2}
Range = {5,0,3}
It is a function as every value in domain has some and unique value mapped to it in Range
b)
Domain = { 7,-6,2}
Range = {5,0,-2,3}
It is not a function as -6 value in domain has two values mapped to it in Range
c)
Domain = { 7,2}
Range = {-6,-7}
It is a function as every value in domain has some and unique value mapped to it in Range
d)
Domain = { 7,-6}
Range = {5,0,3}
It is not a function as 7 value in domain has two values 3 and 5 mapped to it in Range

The value of h(3) is 120 ⇒ B
Step-by-step explanation:
To find the value of f(x) at x = a, do that
- Substitute x by a
- Find the value of f(a)
∵
- To find h(3) substitute x by 3
∴
∵ = 81
∵ (3)² = 9
- Substitute them in the function above
∴ h(3) = 2(81) - 4(9) - 2(3)
∴ h(3) = 162 - 36 - 6
∴ h(3) = 120
The value of h(3) is 120
