In order to solve these sort of problems, we can set up 2 equations from the 2 statements.
We can subsitute the value of f, our first equation, into the second equation and solve like this:
Then we put the the son's age, 20, back into one of our equations and solve for the other value.
Thus, the father is 45 years old and the son is 20 years old.

Simplifying the radical, we have <u />
The second derivative at the point (2,2) is 34/9
<u>Explanation:</u>
<u></u>
2x⁴ = 4y³
2x⁴ - 4y³ = 0
We first need to find dy/dx and then d²y/dx²
On differentiating the equation in terms of x
dy/dx = d(2x⁴ - 4y³) / dx
We get,
dy/dx = 2x³/3y²
On differentiating dy/dx we get,
d²y/dx² = 2x²/y² + 8x⁶/9y⁵
d²y/dx² = 34/9
Therefore, the second derivative at the point (2,2) is 34/9
