Step-by-step explanation:
1/2 + 3/4
= 2/4 + 3/4
= 5/4
= 1 and 1/4 miles
Relliable = 1.5 x 30=45
speedy = 1.1 x 30 +11.5= 44.50
city = 1.25x30+8=45.50
so reliable is the cheapest
Answer:
Interval notation: Range = (1,9)
Words notation: Range is between 1 and 9.
Inequality notation: Range = {f(x)| 1 < f(x) < 9}
Step-by-step explanation:
The given function is

We need to find the range of f(x) for the domain -2 < x < 6 .
At x=-2,

At x=6,

So, the range of the function is 1 < f(x) < 9. It can be written as
Interval notation: Range = (1,9)
Words notation: Range is between 1 and 9.
Inequality notation: Range = {f(x)| 1 < f(x) < 9}
