After a little manipulation, the given diff'l equation will look like this:

e^y * dy = (2x + 1) * dx.
                                                             x^2
Integrating both sides, we get e^y = 2------- + x + c, or e^y = x^2 + x + c
                                                               2

Now let x=0 and y = 1, o find c:

e^1 = 0^2 + 0 + c.  So, c = e, and the solution is e^y = x^2 + x + e.

What is the directrix of the following graph?<br> X = -3<br> Y= 3<br> Y = -3<br> X = 3
kaheart [24]

Answer:

y = 3

Step-by-step explanation:

The vertex of the parabola is (1,4) and the axis of the parabola is parallel to the positive y-axis.

So, the equation of the parabola will be (x - 1)² = 4a(y - 4) ....... (1)

Now, we have to get the value of a since the equation id the directrix is y = 4 - a.

Now, the parabola passes through the point (3,5) {Obtained from the graph).

Therefore, from equation (1), we get, 2² = 4a × 1, ⇒a = 1

Therefore, the equation of the directrix is y = 4 - 1 = 3. (Answer)
