Suppose f(x)=sin(pi cos(x))
On any interval where the inverse function y=f^-1(x) exists, the derivative of f^-1(x) with respect to x is:
A. -1/(cos(pi cos x)
B. -1/(pi sin(x) cos( pi cos(x)))
C. -1/(pi sin(y) cos(pi cos(y))
D. -1/(cos(pi cos(y))
E, -1/(sin(y) cos(pi cos(y))

b

Step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
