Answer:
(-2, 0) and (4, -6)
Explanation:
You want the ordered pair solutions to the system of equations ...
- f(x) = x² -3x -10
- f(x) = -x -2
Solution
We can set the f(x) equal, rewrite to standard form, then factor to find the solutions.
x² -3x -10 = -x -2
x² -2x -8 = 0 . . . . . . . add x+2
(x +2)(x -4) = 0 . . . . . . factor
The values of x that make the product zero are ...
x = -2, x = 4
The corresponding values of f(x) are ...
f(-2) = -(-2) -2 = 0
f(4) = -(4) -2 = -6
The ordered pair solutions are (-2, 0) and (4, -6).
