vodomira [7]

Answer:

D. 5 +6k/n

Step-by-step explanation:

The width of the interval is (5 -2) = 3. The width of one of n parts of it will be ...

3/n

Then the difference between the left end point of the interval and the value of x at the right end of the k-th rectangle will be ...

k·(3/n) = 3k/n

So, the value of x at that point is that difference added to the interval's left end:

2 + 3k/n

The value of the function for this value of x is ...

f(2 +3k/n) = 2(2 +3k/n) +1 = (4 +6k/n) +1

= 5 +6k/n

Given that the function g is defined by the rule g(x)=3-2x,determine the following

Illusion [34]

Answer:

The value of g(a) is:

g(a) = 3 - 2a

Step-by-step explanation:

Given

As the function g(x) is given by

$g(x)=3-2x$

To determine

g(a) = ?

In order to determine g(a),

substitute x = a in the function g(x) = 3 - 2x

g(x) = 3 - 2x

g(a) = 3 - 2(a)

g(a) = 3 - 2a

Therefore, the value of g(a) is:

g(a) = 3 - 2a
