Answer:
Step-by-step explanation:
The roots (zeros) of the function are (1, 0) and (3, 0). The point (2, 2) is the vertex, the maximum in this case.
The domain of any polynomial function is "all real numbers".
The range is y ≤ 2, not y < 2.
Answer:
It costs $25 for a parent and $6 for a child
Step-by-step explanation:
Let x be the cost it takes for an adult to enter, and y be the cost it takes for a child to enter then...
x+y=31
150x+225y=5100
We can write the first equation in terms of x by subtracting y from both sides...
x=31-y
Now, we can solve the system of equations by substitution (substitute 31-y for x)...
150(31-y)+225y=5100
Distribute the 150 to the terms inside of the parentheses
150(31)-150(y)+225y=5100
4650-150y+225y=5100
Combine like terms
4650+75y=5100
Subtract 4650 from both sides
75y=450
Divide both sides by 75
y=6
Plug 6 back in for y to solve for x:
x=31-y=31-6=25
It costs $25 for a parent and $6 for a child
