Which statements about the graph of the function f(x) = –x2 – 4x + 2 are true? Check all that apply.
2 answers:
Remark
There is nothing like a graph to settle arguments about which property is to be checked.
Property One
The graph's domain is (-∞<x<∞) there are no restrictions. So property 1 is false.
Property two
The graph says that property two is true. You could complete the square to confirm it. When you do you get
y = -(x^2 + 4x) + 2
y = -(x^2 + 4x + 4) + 2 + 4
y = -(x + 2)^2 + 6 So the y value must be less that 6 ( or equal to 6)
Property Three
Property 3 is true if you are referring to the domain and neither -2 nor - infinity are included.
Property Four
Property Four is not true, It begins to decrease when x>-2 to + infinity
Property Five
It is positive (2).

Answer:
240 miles
Step-by-step explanation:
Given that:
Charges offered by Prestige car rentals for renting a midsize vehicle:
Fixed charges = $47
Per mile charges for renting a midsize vehicle = $0.07
Charges offered by Gateway Auto for renting a midsize vehicle:
Fixed charges = $35
Per mile charges for renting a midsize vehicle = $0.12
To find:
Number of miles for which both the companies charge the same price?
Solution:
Let the number of miles for which both the companies will charge the same price = miles
Charges for one mile by Prestige car rentals = $0.07
Charges for miles by Prestige car rentals = $0.07
Total charges by Prestige Car rentals = $47 + $0.07
Charges for one mile by Gateway Auto = $0.12
Charges for miles by Gateway Auto = $0.12
Total charges by Gateway Auto = $35 + $0.12
As per question statement, the charges are same:
