a) (x+8)(x-2)
b) (x+7)(x-7)

If f(x)=2x-6 and g(x)=3x+9, find (f-g)(x)

F(x) = 1/x g(x)=x-4 can you evaluate (g*f)(0) ? why or why not?

Determine the domain and range of the given function. the domain is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}. the range is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}.
