find the domain and range of the function f (x)=(x^2-16)/(x-4)

fx=x2-16x-4fx can be defined for all x except x=4.At x=4, fx cannot be defined.Thus, domain=R-4Range: R set of all real numbers

  • -2

x-4 cant be equal to zero

domain R-{4}

range

(x+4)(x-4)/x-4
x+4 
Range : R

  • -5
domain = R-{4}
