Which answer is the correct restriction on the domain? x-7/x+4 ÷ x/x+3 a. x=/7,0 b. x=/7,-3 c. x=/-4,0 d. x=/-4,-3 plz

Remember that dividing by a fraction is the same as multiplying by the reciprocal (or the reverse) of the fraction on the bottom. A restriction on the domain means that x can not be that value. This occurs when the denominator is zero. If (x+4) = 0 or x = o then the denominator will be zero so the restrictions are x = -4,0. The answer is c.
