Transcribed Image Text:**Using the Factor Theorem to Determine Factors**
This exercise utilizes the Factor Theorem to ascertain if \(x - c\) is a factor of \(f(x)\).
1. **Problem 1:**
- Given: \( f(x) = x^4 - 21x^2 - 100 \); \( x - 10 \)
- Options:
- A) Yes
- B) No
2. **Problem 2:**
- Given: \( f(x) = 7x^4 + 20x^3 - 3x^2 + x - 3 \); \( x + 3 \)
- Options:
- A) Yes
- B) No
In this exercise, to determine if \(x - c\) is a factor of \(f(x)\), substitute \(c\) into the polynomial \(f(x)\). If the result is zero, then \(x - c\) is a factor.
