Which is the graph of y = cos(x) + 3?
1 answer:
Answer:
On a coordinate plane, a cosine curve has a maximum of 4 and a minimum of negative 2.
Step-by-step explanation:
Given:
To find: maximum and minimum of the cosine curve
Solution:
A coordinate plane is a two-dimensional plane formed by the intersection two axis: x-axis and y-axis.
These two axes are perpendicular to each other.
As per the image drawn below,
a cosine curve has a maximum of 4 and a minimum of negative 2 on the coordinate plane.

Answer:
0 is an inflection point
1/4 is a local maximum.
Step-by-step explanation:
To begin with you find the first derivative of the function and get that
to find the critical points you equal the first derivative to 0 and get that
To find if they are maximums or local minimums you use the second derivative.
since is neither an inflection point, and since
then 1/4 is a maximum.
Answer:
No solution
Step-by-step explanation:
So we have the equation:
First, subtract 20 from both sides:
Now, we can stop. Recall that absolute value will always <em>always</em> give a positive answer.
Since this equals -16, this means that there is no solution.
And we're done!
