Answer:
There is no short answer.
Step-by-step explanation:
To find to intervals which f(x) increases or decreases, we first need to find it's derivative.
The function is increasing when it's value is > 0 and decreasing when it's value is < 0.
If we take a look at this graph, cosx+sinx is positive when they are both positive or when cosx is greater then sinx on the negative part.
I hope this answer helps.
Answer:
The equation is
Step-by-step explanation:
If we want a line parallel to the line in the problem it will have the same slope. The equation given in the problem is already in slope intercept form so we can take the slope for the new equation directly from this equation.
The slope-intercept form of a linear equation is:
Where m is the slope and b is the y-intercept value.
Therefore the slope is
We can now use the point-slope formula to write the equation of the parallel line:
The point-slope formula states:
Where m is the slope and is a point the line passes through.
Substituting the information from the problem gives:
Or, we can solve for y to put the equation in slope-intercept form:
