Generalize Exercise 87: Show that if the horizontal line y = c intersects the graph of (x)
Question:
Generalize Exercise 87: Show that if the horizontal line y = c intersects the graph of ƒ(x) = x2 + rx + s at two points
Figure 26
Data From Exercise 87
Show that if the quadratic polynomial ƒ(x) = x2 + rx + s takes on both positive and negative values, then its minimum value occurs at the midpoint between the two roots.
Transcribed Image Text:
x1 + x2 (x₁, f(x1)) and (x2, f(x2)), then f takes its minimum value at the midpoint M = 2 (Figure 26).

Hi there! Are you looking for a committed, reliable, and enthusiastic tutor? Well, teaching and learning are more of a second nature to me, having been raised by parents who are both teachers. I have done plenty of studying and lots of learning on many exciting and challenging topics. All these experiences have influenced my decision to take on the teaching role in various capacities. As a tutor, I am looking forward to getting to understand your needs and helping you achieve your academic goals. I'm highly flexible and contactable. I am available to work on short notice since I only prefer to work with very small and select groups of students. Areas of interest: Business, accounting, Project management, sociology, technology, computers, English, linguistics, media, philosophy, political science, statistics, data science, Excel, psychology, art, history, health education, gender studies, cultural studies, ethics, religion. I am also decent with math(s) & Programming. If you have a project you think I can take on, please feel welcome to invite me, and I'm going to check it out!
