지수로그 킬러, 그 전설의 시작 [26 6월 22번]

Join Membership:    / @수학한수   Question 22 from the June 2026 Mock Exam stands out for its high-difficulty design, which goes beyond a simple list of formulas to simultaneously demand the geometric essence and insight of exponential and logarithmic functions. The core of this explanation lies in defining the locus of point A as y = 2^(x+1) and determining point B through the relationship between the slope -1 and translation. It explains how to reach the correct answer by utilizing the area condition without directly calculating the coordinates. 00:00 Preview and Introduction to the Question 00:25 Reading the Question and Graph Analysis 01:24 Solving the System of Equations and Deriving the Coordinates of Point A 02:07 Relationship Between Point B's Coordinates and Translation (Locus Analysis) 04:11 Application of the Area Condition for Triangle AOB 05:01 Final Answer and Wrap-up #MathHansu #JuneMockExam #Question22
