Honorlock Essay Prompt:Write a response essay about your personal experiences with growth mindset and fixed mindset. In your essay, you must: Describe a time in your life when you did not use a growth mindset (a fixed-mindset moment). Explain what you believed in that moment, how you responded to the situation, and what the outcome was. Describe a time in your life when you did use a growth mindset. Explain what you did differently, how you handled challenge/feedback/effort, and what the outcome was. Explain how you can maintain a growth mindset in the future. Include at least two specific strategies you will use (for example: how you will respond to mistakes, how you will handle feedback, or how you will keep motivation when something feels difficult). Suggested Structure (Recommended) Introduction (1 paragraph): Briefly explain growth mindset vs. fixed mindset and state your main point (thesis). Preview your two experiences and your plan for maintaining a growth mindset. Body Paragraph 1: Fixed-mindset moment (what happened, what you believed, how it affected your choices/outcome). Body Paragraph 2: Growth-mindset moment (what happened, what you believed, what you did, what changed). Body Paragraph 3: Maintaining growth mindset (two or more strategies + why they will work for you). Conclusion (1 paragraph): Summarize key insights and explain how your mindset will shape your future learning and goals.

If it does, then find it; otherwise explain why it does not. (10 pts) Does the function  f ( x 1 , x 2 ) = − x 1 2 + x 1 x 2 − x 2 2 − x 2 + 1 {“version”:”1.1″,”math”:”f(x_1,x_2)=-x_1^2+x_1x_2-x_2^2 – x_2 +1 “}{“version”:”1.1″,”math”:”f(x_1,x_2)=2x_1^2+4x_1x_2+2x_2^2 – x_1 +3 “}have a minimizer or a maximizer? If it does, then find it; otherwise explain why it does not. Problem 6. (15 pts)  Bracket the minimizer of  f = 2 x 1 2 + x 2 2 {“version”:”1.1″,”math”:”f=2x_1^2+x_2^2 “} on the line passing through the point  x ( 0 ) = [ − 5 0 ] ⊤ {“version”:”1.1″,”math”:”x^{(0)}=\left[\begin{array}{cc} -5 & 0 \end{array}\right]^{\top}”} in the direction  d = [ 10 10 ] ⊤ {“version”:”1.1″,”math”:”\( d =\left[\begin{array}{cc} 10 & 10 \end{array}\right]^{\top}\)”}.
