y = x^3 + 2x^2 + 2
Flip x and y. That's the inverse function
x = y^3 + 2y^2 + 2
Derive implicitly and solve for dy/dx
dx = 3y^2 * dy + 4y * dy
dx = (3y^2 + 4y) * dy
1 / (3y^2 + 4y) = dy/dx
We started with (1 , 5), so let's flip them to (5 , 1)
y = 1
1 / (3 * 1^2 + 4 * 1) =>
1 / (3 + 4) =>
1/7

From alex: f'(x) = 3x^2+4x
f'(1)=7

f'(x) = 3x^2+4x
f'(1)=7
>(f^1)'(5)=1/7
