RANGE gives you the possible y values. [4, ∞) means the lowest y value - y coordinate of the vertex is 4 and the y is increasing from 4 upwards towards infinity. The graph opens up.
DOMAIN gives you the possible x's. As you can see no restrictions.
Answer:
Domain={-2,2,3,5}
Range={-3,1,7,12}
Step-by-step explanation:
The given ordered pairs are (5,12)(3,-3),(-2,7)(2,12)(5,1).
The domain refers to the set of all the first coordinates(x-values).
Domain={-2,2,3,5}
The range refers to the set of all the second coordinates (y-values).
Range={-3,1,7,12}
Note that, we do not repeat elements in a set.
Do not list the 5 in the domain twice.
The same applies to the 12 in the range
Answer:
5
Step-by-step explanation:She runs around the outer border and it measures 2 feet across so you just get 5 because 5 seems right
Answer:
7 weeks
Step-by-step explanation:
John saves f(x) = 60+5x
Sarah saves g(x) =x^2 +46
They save the same amount of money
Set the equations equal
60+5x =x^2 +46
Subtract 60 from each side
60+5x -60 =x^2 +46-60
5x= x^2 - 14
Subtract 5x from each side
5x -5x= x^2-5x - 14
0 = x^2-5x - 14
Factor
0 = (x-7) (x+2)
Using the zero product property
x-7=0 x+2 =0
x=7 x=-2
Since we cannot have negative weeks
x=7
