1. Problem Description
The problem asks to find the equation of the tangent line to the curve defined by the function at the point where the y-coordinate (ordinate) is equal to
1.
2. Solution Steps
First, we need to find the x-coordinate corresponding to the given y-coordinate of
1. That is, we need to solve the equation $f(x) = 1$ for $x$.
Let's look for simple integer solutions. If , we have .
If , we have .
If , we have .
If , we have .
If , we have .
If , we have .
However, there is an error in the transcription of the original image. It is possible that the problem intended for to intersect the y value at a simple integer.
Let's assume the y-coordinate (ordinate) is actually -
2. $-x^3 + 3x - 2 = -2$
or
or
or .
Thus, we found a simple integer solution .
Now we need to find the derivative of :
Next, we evaluate the derivative at to find the slope of the tangent line at that point:
So the slope of the tangent line at is .
The point is .
Using the point-slope form of a line, , we have:
3. Final Answer
Assuming the y-coordinate given is -2 (instead of 1), the equation of the tangent line is .
