Answer:
(-2/3, 2), (1/2, 2)
Step-by-step explanation:
A graphing calculator can show you those points: (-2/3, 2), (1/2, 2).
__
Put the given value in the equation and solve for x.
2 = f(x)
2 = (x -2)/(3x^2 +x -2)
2(3x^2 +x -2) -(x -2) = 0 . . . . . multiply by the denominator; put in standard form
6x^2 +x -2 = 0 . . . . . collect terms
(3x +2)(2x -1) = 0 . . . factor
Solutions are values of x that make the factors zero:
x = -2/3, x = 1/2
Then the points on the graph are (-2/3, 2) and (1/2, 2).
