    y=-5n-5

    switch the signs to find inverse and solve for y

    n=5y-5

    n+5=5y

    divide by 5

    1/5n+1=y

    that's your inverse my dude

    -n - 5

    f^-1 (x) = 5 or (-n - 5) / 5

    Step-by-step explanation:

    g (n) = - 5n - 5

    RS | SR

    Replace: y = - 5n - 5

    Switch n & y: n = - 5n - 5

    Solve for y:

    n = - 5y - 5. Isolate y

    +5 + 5

    -1 (n + 5) = (-5y) - 1 Multiply each side by

    -1 so that y isn't

    negative.

    -n - 5 = 5y Divide 5 on each side. 5

    5 5 comes from 5y

    -n - 5

    y = 5

    Replace y with f^-1 (x):

    -n - 5

    f^-1 (x) = 5
