Question

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

Answer 1

Answer:

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

so y = 3x - 3

since 3x + 6 is on the bottom,

$3x + 6\neq 0\\3x\neq -6\\x\neq -2$

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