(a)
Answer to Problem 75RE
The slope of the graph function
Explanation of Solution
Given information:
Calculation:
Consider the function:
The slope of graph of the function
By using this formula:
The slope of graph of the function at
Since,
Divide the denominator and numerator by
Hence, the slope of the graph function
(b)
To calculate:
The tangent line to graph the following equation:
(b)
Answer to Problem 75RE
The equation of tangent line at the point
Explanation of Solution
Given information:
The equation of straight line is
Know that,
For the straight line, the slope at every point on it is similar.
By using the equation of the tangent:
Then, satisfy the equation:
Hence, the equation of tangent line at the point
