Dx? 1. f (x) = x2 and thus, as we will learn, f ′(x) = 2x. find a differential equation for f . for this example, it should be of the form f ′(x) = f (x) ∗ g(x) where your task is to find g(x). g will not be defined at x = 0, but don’t worry about that right now.

This boils down to simple algebraic manipulation.

So one possible ODE (the simplest, in fact) is

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
