Question

Which graph represents the function​
there are 2 more graphs but it won't add it

Answer 1

`f(x) = 9x^2+9x - 18/3x + 6\\= 9(x^2 + x - 2)/3(x+2)\\= 3(x^2+x-2)/x+2\\= 3(x+2)(x-1)/x+2\\= 3x - 3`

so y = 3x - 3

since 3x + 6 is on the bottom,

`3x + 6\\eq 0\\3x\\eq -6\\x\\eq -2`

so this means it should be the graph of y = 3x - 3, but with a hole at (-2, -9)
