Question
**Question:**

c. TRUE or FALSE. The tangent line for a function \( g(x) \) at the point \( x = a \) can be found using the following formula: 

\[ y - g'(a) = g(a)(x - a) \]

If true, explain why. If false, give the correct formula for the tangent line at a point.

**Explanation:**

The statement is **FALSE**. The given formula is incorrect for finding the equation of the tangent line to the function \( g(x) \) at the point \( x = a \).

**Correct Formula:**

The correct formula for the tangent line to the function \( g(x) \) at the point \( x = a \) is:

\[ y - g(a) = g'(a)(x - a) \]

Where:

- \( g(a) \) is the value of the function at \( x = a \).
- \( g'(a) \) is the derivative of the function at \( x = a \), representing the slope of the tangent line.
- \( (x - a) \) indicates the horizontal displacement from the point of tangency.
