APFIVE Valid Solutions for a Piecewise Function
For the piecewise function given above, solve for x in the equation when the function equals the specified value: solve $$2*x+1 = 7$$ for $$x<3$$ and $$x^2-4*x+3 = 0$$ for $$x \ge 3$$, then determine the valid solution.
| Domain | Equation |
|---|---|
| $$x < 3$$ | $$2*x+1$$ |
| $$x \ge 3$$ | $$x^2-4*x+3$$ |
A
The only solution is $$x = 3$$.
B
The solutions are $$x = 1$$ and $$x = 3$$.
C
There are no solutions.
D
The only solution is $$x = 1$$.
