Answer:

B

Explanation:


a(x) = 2-8x\\

is the same as saying:


\\y = 2-8x

when ur asked to find the inverse of a function, just put x in place of y, and y in place of x, and solve for y.

let me demonstrate,


\\y = 2-8x\\x = 2 - 8y\\x -2 = -8y\\2-x = 8y\\\\y = (2-x)/(8) \\

and yeah that's it, that's how u get the inverse of a function
