Step-by-step explanation:

[tex]a(x) = 2-8x\\[/tex]

is the same as saying:

[tex]\\y = 2-8x[/tex]

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,

[tex]\\y = 2-8x\\x = 2 - 8y\\x -2 = -8y\\2-x = 8y\\\\y = \frac{2-x}{8} \\[/tex]

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