Answer:
For a function y = f(x), the range is the set of all the possible values of y.
In the question you wrote:
y = secx - 2
This can be interpreted as:
y = sec(x - 2)
or
y = sec(x) - 2
So let's see each case (these are kinda the same)
If the function is:
y = sec(x - 2)
Firs remember that:
sec(x) = 1/cos(x)
then we can rewrite:
y = 1/cos(x - 2)
notice that the function cos(x) has the range -1 ≤ y ≤ 1
Then for the two extremes we have:
y = 1/1 = 1
y = 1/-1 = -1
Notice that for:
y = 1/cos(x - 2)
y can never be in the range -1 < x < 1
As the denominator cant be larger, in absolute value, than 1.
Then we can conclude that the range is all reals except the interval:
-1 < y < 1
If instead the function was:
y = sec(x) - 2
y = 1/cos(x) - 2
Then with the same reasoning, the range will be the set of all real values except:
-1 - 2 < y < 1 - 2
-3 < y < -1
Answer:
63.5 feet/minute
Step-by-step explanation:
She first descended 1,024 feet in 17 minutes
Then she descended 500 feet in 7 minutes
The total feet descended is 1,024 + 500 = 1,524 feet
The total time to descend is 17 + 7 = 24 minutes
The average rate of change in altitude is
Altitude descended / time
1,524 feet / 24 minutes
63.5 feet /minute
Answer:
The Obvious
Euler graph all connects almost like a circle
A tree graph looks like it branches off each other with no line connect in a circle like form
