Use a calculator to graph the function. Then, using the graph, give three points on the graph of the inverse with the y-coordinates given. f(x) = x3 + x − 9, y = 0, 1, 2

Answer 1

y=x^3 + x -9

switch x and y to get the inverse x=y^3 + y -9

when y=0 x=-9 in the inverse

when y=1, x=1^3 +1 -9 = -7

when y=2, x = 2^3 + 2 -9 = +1

those are the points (-9,0), (-7, 1) and (1,2) on the graph of the inverse
