Question
![**Title: Exploring Taylor Series Expansions for Multivariable Functions**
**Introduction:**
In this section, we explore the Taylor series expansions for a given multivariable function at a specific point. The task is to find the first-order and second-order Taylor formulas for the function \( f(x, y) = 7e^{(x+y)} \) at the point \( (0, 0) \).
**Instructions:**
Use symbolic notation and fractions where needed to express each Taylor polynomial.
**First-Order Taylor Formula:**
\[ f(x, y) = \] [First-Order Taylor Polynomial] \( + R_1(0, h) \)
**Second-Order Taylor Formula:**
\[ f(x, y) = \] [Second-Order Taylor Polynomial] \( + R_2(0, h) \)
**Explanation:**
1. **Taylor Series Expansion:** A Taylor series approximates a function near a point using polynomials. The first-order expansion uses linear terms, whereas the second-order expansion includes quadratic terms.
2. **Function and Point:** Here, the function is \( f(x, y) = 7e^{(x+y)} \), and we are expanding around the point \( (0, 0) \).
3. **Error Terms:** \( R_1(0, h) \) and \( R_2(0, h) \) represent the remainder (error) of the first- and second-order approximations, respectively.
By systematically deriving these expansions, one can approximate the behavior of the function near the specified point and gain insight into its local properties.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5daf203e-fcc8-4212-add5-200827e740e3%2Fe78faeaf-aed1-489b-82fc-0376d88261fc%2Ffch2uv9_processed.png&w=3840&q=75)
