Question

Which function is the inverse of f(x) equals negative 5X -4

Answer 1

Answer:

f inverse x = -x+4/5

Step-by-step explanation:

Answer 2

Answer:

f^-1(x) = -1/5 x - 4/5

Step-by-step explanation:

f(x) = -5x - 4

Replace f(x) with y.

y = -5x - 4

Switch x and y.

x = -5y - 4

Solve for y.

5y = -x - 4

y = -1/5 x - 4/5

Replace y with f^-1(x).

f^-1(x) = -1/5 x - 4/5
