1. Consider the family of curves described by: X2 + xy + ay2 = b. Remember to justify your answers. A. Let :1 =1 and b = 7. Find the two X-intercepts. B. Let a =1 and b= 7. Using the two points you found in part A, show that the tangents to the curve at these points are parallel, and find the common slope. C. A given curve in the family x2 +ch+ay2 =b has a tangent line at point (1, 3) with slope HI What are the values of a and b? Copyright 2021 Apex Learning. See Terms of Use for further information.
