Answer:
When writing an inequality from a graph, there are a few things we need to do:
Determine the equation of the line. This gives us the general form of our inequality once we remove the equal sign.
Note whether the line is dotted or solid. ...
Use the graph's shading to determine which way you
I guess you mean the derivative of:
√7x + √2x, if so then:
Remember that the derivative of √u = 1/(2√u) . u'
if 7x = u, then u' = 7 , hence the derivative of √7x is 7/(2√7x)
Use same logic for √2x and you will find:
y' = 7/(2√7x) + x/√2x
Given:
The expressions are:
and 
To find:
The difference of and .
Solution:
Difference of and is written as:
On simplification, we get
Therefore, the difference of and is 
.
