Answer:
$0.75
Step-by-step explanation:
Given:
The function is:

To find:
The result of the operation
.
Solution:
If
, then the graph of f(x) is reflected across the x-axis to get the graph of g(x).
We have,

The given operation is:

So, it will result in a reflection across the x-axis.
Therefore, the correct option is A.
Answer:
we can use centeroid formula of a triangle
that is (x1+x2+x3)/3
hope that helps : )
Answer:
Increasing if f' >0 and decreasing if f'<0
Step-by-step explanation:
Difference quotient got by getting
will be greater than 0 if function is increasing otherwise negative
Here h is a small positive value.
In other words, we find that whenever first derivative of a function f(x) is positive the function is increasing.
Here given that for x1, x2 where x1<x2, we have
if f(x1) <f(x2) then the function is decreasing.
Or if x1<x2 and if f(x1) >f(x2) for all x1, and x2 in I the open interval we say f(x) is decreasing in I.
