Answer: e x.
- A e<sup>x</sup>
- B e<sup>−x</sup>
- C x
- D 1
Correct answer: A. e<sup>x</sup>
Explanation: IF = e<sup>∫P dx</sup> = e<sup>∫1 dx</sup> = e<sup>x.</sup>
The general solution y=Ax² represents an entire FAMILY of curves, one for each value of the arbitrary constant A; a particular solution (fixed by an initial condition) selects exactly one curve from this family.
