Can anybody help me solve 6 through 8

Question

I have nearly tried 5 different times to figure out these questions, and I am really struggling with these calculus questions. These are the only questions I'm struggling with right now. I might just be overthinking it though. 😕

6. Find the equation of the tangent line to the inverse of f(x) = x^5 + 2x^3 + x - 4 at the point (-4,0).

7. Find the equation of the tangent line to the inverse of f(x) = 7x + sin(2x) at the point (0,0).

8. Find the equation of the tangent line to the inverse of f(x) = x^3 + 8x + cos(3x) at the point (1,0).
