What is the domain of the function f(x)= x^2-16/x-4

Step-by-step explanation:

this is a rational function thus the domain is all real numbers except the values which make zero to denominator

hence x-4=0 ;x=4

the domain of that function is R- {4}

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
