Write the equation of the tangent line with the quotient rule at a point

The video tutorial explains how to find the point and slope for an attention line, calculate the derivative of a function, and evaluate it at a specific point. It concludes with writing the equation of the line using the derived slope and point.

What is the y-coordinate when x is equal to 1 in the given equation?

• 1/2

• 3/2

• 2/3

• 1/3

What is the first step in finding the derivative of a function?

• Finding the slope

• Identifying the constant

• Simplifying the expression

• Rewriting the function

What is the derivative of a constant?

• Undefined

• One

• Zero

• The constant itself

Why is it important to use brackets and parentheses when calculating derivatives?

• To make it easier to read

• To make the expression look neat

• To avoid calculation errors

• To simplify the expression

What is the result of evaluating the derivative at x = 1?

• -1/9

• 1/9

• -1/3

• 1/3

What is the equation of the line derived from the given derivative?

• y - 1/3 = -1/9(x - 1)

• y + 1/3 = -1/9(x + 1)

• y + 1/3 = 1/9(x + 1)

• y - 1/3 = 1/9(x - 1)

What is the purpose of finding the derivative in this context?

• To find the slope of the tangent line
