Answer:
the largest interval of x values where f(x) is increasing is (-1,1).
Step-by-step explanation:
the domain of f(x) is all real numbers.
As we can conclude from the table that the function f(x) is decreasing from (-3, -1) and the function is increasing from (-1, 1) .
Graphically we can also show this that for the x-values in (1,-1) function is increasing.
Answer:
descriptive statistics
Step-by-step explanation:
Answer 420.
a, is the first term. d is difference.
Since this is an arithmetic progression, I use this formula.
Un = nth term
Sn = sum of terms.
First find the number of terms, which is 20.
Then use the second formula to find the sum.
The mode is the number that occurs most frequently in the set.
Putting the numbers in order will help us find the mode.
18,18,21,24,24,24,27,30,30,30
We see that 24 and 30 have an equal number of occurrences in the data set, meaning that 24 and 30 are both modes.
Answer:
y=-1/2+2
Step-by-step explanation:
the y intercept is 2
Its negative because the slope is going down
1/2 because down 1 right 2
