The graph of is differentiable on
The graph of
is not differentiable at
because it is a point of discontinuity, at
because of a sharp corner, at
because it is a point of discontinuity, and at

Finding an equation of a line tangent to the graph of a function
The equation of a tangent line to a curve of the function
at
is derived from the point-slope form of a line,
The slope of the line is the slope of the curve at
and is therefore equal to
the derivative of
at
The coordinate pair of the point on the line at
is
If we substitute into the point-slope form, we have
The equation of the tangent line is

Step 1: Find the mean. To find the mean, add up all the scores, then divide them by the number of scores. ...
Step 2: Find each score's deviation from the mean. ...
Step 3: Square each deviation from the mean. ...
Step 4: Find the sum of squares. ...
Step 5: Divide the sum of squares by n – 1 or N.
The sample of 16 students is taken. The average age in the sample was 22 years with astandard deviation of 6 years. Construct a 95% confidence interval for the age of the population.
Bhartdarshan' is an internet-based travel agency wherein customer can see videos of the cities they plant to visit. The number of hits daily is a normally distributed random variable with a mean of 10,000 and a standard deviation of 2,400
