Answer:

<u>3(x^3 + 5x)^2 - 4 </u>   (please mark brainliest)

Step-by-step explanation:

plug g equation into x values of f equation

f equation = 3(x)^2 - 4

                        ^g goes here

So....

Find the domain for the particular solution to the differential equation dy dx equals the quotient of 3 times y and x , with ini
Svetach [21]
For this case we have the following difference equation:
 dy / dx = 3xy&#10;
 Applying separable variables we have:
 dy / y = 3xdx&#10;
 Integrating both sides we have:
 \int\ ({1/y}) \, dy =  \int\ {3x} \, dx
 ln (y) = (3/2) x ^ 2 + C&#10;
 applying exponential to both sides:
 exp (ln (y)) = exp ((3/2) x ^ 2 + C)&#10;&#10; y = C * exp ((3/2) x ^ 2)
 For y (1) = 1 we have:
 C = 1 / (exp ((3/2) * 1 ^ 2))&#10;&#10;C = 0.2
 Thus, the particular solution is:
 y = 0.2 * exp ((3/2) x ^ 2)&#10;
 Whose domain is all real.
 Answer:
 y = 0.2 * exp ((3/2) x ^ 2)
 Domain: all real numbers
