PLEASE HELP 25 POINTS

Mathematics
1 answer:
gulaghasi [49]3 years ago
3 0

Hello from MrBillDoesMath!

Answer:

First term =  S(1) = 1

Common difference = S(n+1) - S(n) = 1 -6n

t(n) value:  can't answer this as I don't know what t(n) refers to,



Discussion:

Let S(n)  = 4n - 3n^2  

First term:

S(1) = 4(1) - 3(1)^2 = 4 - 3 = 1


Common difference:

S(n+1) - S(n) =    ( 4(n+1) - 3 (n+1)^2) - (4n - 3n^2)

                    =    (4n + 4 - 3n^2 -6n -3) - 4n + 3n^2                

                            (now cancel common terms)

                   = -6n +  4 - 3 = -6n + 1


S(n+1) = S(n) -6n +  1


Thank you,

MrB

Use the given graph of f to estimate the intervals on which the derivative f ' is increasing or decreasing. (Enter your answers
NARA [144]

The derivative of a function is used to determine whether the function is increasing or decreasing on any intervals in its domain.

Derivative of function f is increasing in interval  (-2 , 1) and (3 , 6)

Derivative of function f is decreasing in interval (1 , 3) and (6 , 9)

If f′(x) > 0 at each point in an interval , then the function is said to be increasing in that interval.

If f′(x) < 0 at each point in an interval , then the function is said to be decreasing on that interval.

By observing graph, it is observed that slope  of function f is positive in interval  (-2 , 1) and (3 , 6) . Hence, derivative of  function f is increasing in interval  (-2 , 1) and (3 , 6)

By observing graph, it is observed that slope  of function f is negative in interval  (1 , 3) and (6 , 9) . Hence, derivative of  function f is decreasing in interval  (1 , 3) and (6 , 9).
