Evaluate the following when x=-3, if possible.
(a)-x
(b)/x/
(c)-x^2
(d)-(1+x)

  • Math -

    I'll do (a):
    substitute -3 for x to get
    -(-3) = 3

    Proceed similarly for the rest. Post your answers for a check if you wish.

  • Math -

    (b)/-3/=/3/
    (c)-3^2=-9
    (d)-(1+(-3))
    is this right? Please help!!
