Answer:
B
Step-by-step explanation:
To find the y- intercept let x = 0
From the table for f(x)
When x = 0 → f(x) = - 4
That is the y- intercept = - 4
Given
g(x) = 3
let x = 0 , then
g(0) = 3 [
= 1 ]
= 3 × 1
= 3
That is the y- intercept = 3
Thus the y- intercept of g(x) is greater → B
As a Bernoulli equation:
Let
. The ODE becomes
![\dfrac{\mathrm d}{\mathrm dx}[x^6z]=-6x^4](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cmathrm%20d%7D%7B%5Cmathrm%20dx%7D%5Bx%5E6z%5D%3D-6x%5E4)
With
, we get
so the solution is
which is valid as long as the denominator is not zero, which is the case for all![x\neq\sqrt[5]{\dfrac{4131}{12}}](https://tex.z-dn.net/?f=x%5Cneq%5Csqrt%5B5%5D%7B%5Cdfrac%7B4131%7D%7B12%7D%7D)
