Inverse scale function image If the line y = 2x-1 intersects with the Y axis at point a, and then the line is translated upward by one unit, and intersects with the curve y = 2 / X at two points B and C, what is the area of triangle ABC
Y = 2x-1 up a unit of y = 2x simultaneous y = 2 / X solution, x = ± 1, y = ± 2
∴A(0,-1),B(1,2).C(-1,-2)
S△ABC=1/2*1*1+1/2*1*1=1
