The diagram shows a section of the curve with equation y = x 4 + 3x 2
Question:
The diagram shows a section of the curve with equation y = −x4 + 3x2 + 4. The curve intersects the x-axis at points A and B. The finite region R, which is shown shaded, is bounded by the curve and the x-axis.
a. Show that the equation −x4 + 3x2 + 4 = 0 only has two solutions, and hence or otherwise find the coordinates of A and B.
b. Find the area of the region R.

As a Business Management graduate from Moi University, I had the opportunity to work as a tutor for undergraduate students in the same field. This experience allowed me to apply the theoretical knowledge I had gained in a practical setting, while also honing my teaching and communication skills.
As a tutor, I was responsible for conducting tutorial sessions, grading assignments and exams, and providing feedback and support to my students. I also assisted with the preparation of course materials and collaborated with other tutors and professors to ensure consistency in teaching and assessment.
