Call the region of Quadrant I completely enclosed by these three functions by Region R. A. In Quadrant I: functions f₁ and f2 have one intersection point; functions f₁ and f3 have one intersection point; functions f2 and f3 have one intersection point. Find the x-coordinates of these three intersection points. B. Labeling the three x-coordinates from Part A as a < b < c: on the interval [a, b], two of these three functions are the "top" and "bottom" functions defining Region R; on the interval [b, c], two of these three functions are the "top" and "bottom" functions defining Region R. Identify the "top" and "bottom" functions defining Region R on the intervals [a, b] and [b, c]. C. Sketch a graph of Region R.arrow_forward1. Let y = x² + 1 and y = −2x + 1. (a) Graph the two functions together on the same plane. Find the points of intersection. (b) Find the area of the region bounded by the line z = −2 on the left, the line x = 2 on the right, and the graphs of the functions y = x² + 1 and y = −2x + 1.arrow_forward

Sketch the graph and the rectangles then estimate the area by using the left endpoints of six subintervals. b. Sketch the graph and the rectangles then estimate the area by using the right endpoints of six subintervals. c. Sketch the graph and the rectangles then estimate the area by using the midpoints of six subintervals. d.

If we visualize the region having "top" and "bottom" boundaries, express each as functions of a and provide the interval of -values that covers the entire region. "top" boundary g2 (x) - "bottom" boundary 9₁(x) = interval of values that covers the region 2. If we visualize the region having "right" and "left" boundaries, express each as functions of y and provide the interval of y-values that covers the entire region. "right" boundary f2(y) = "left" boundary f₁(y) = interval of y values that covers the regionarrow_forward7. The region D above lies between the two red lines and 2 -². It can be described in two 1 the red parabola y: = ways. 1. If we visualize the region having "top" and "bottom" boundaries, express each as functions of x and provide the interval of x-values that covers the entire region. "top" boundary g₂(x) = "bottom" boundary g₁(x): interval of a values that covers the region = 2.
