Question
Let y=f(x) be a cubic polynomial with leading coefficient, a=1; containing the ordered pair (2,0) and a zero at x=2i. Find the function, f(x), that has these characteristics.
**MAT 171: Sections 2.3–2.5 Lab** 2. Let \( y = f(x) \) be a cubic polynomial with leading coefficient, \( a = -1 \); containing the ordered pair \( (2, 0) \), and a zero at \( x = 2i \). Find a function, \( f(x) \), that has these characteristics. 3. Given: \( f(x) = (3x^5 - 5x^2 + 3)(x^2 - 6x - 6) \) a. What is the parent function? b. How many zeros will this function have in total (both real and complex)? c. What is the domain of this function, in interval notation? d. What is the range of this function, in interval notation? 4. Find all zeros of the function, \( g(x) = x^3 - 7x^2 - x + 87 \), given that \( 5 + 2i \) is a zero. **Note**: The document is focused on polynomial functions, requiring the analysis of characteristics like zeros, domain, and range.
