Question

Which graph represents the function of f(x) = the quantity of 9 x squared minus 36, all over 3 x plus 6?

graph of 3 x plus 6, with discontinuity at 2, 12
graph of 3 x plus 6, with discontinuity at negative 2, 0
graph of 3 x minus 6, with discontinuity at negative 2, negative 12
graph of 3 x minus 6, with discontinuity at 2, 0

Answer 1

its C i got it right on the thingy

Explanation:

Answer 2

f ( x ) = ( 3 x + 6 ) ( 3 x - 6 ) / ( 3 x + 6 ) = 3 x - 6
and for domain : 3 x + 6 ≠ 0
3 x ≠ - 6
x ≠ - 2
Answer:
C ) graph of 3 x - 6, with discontinuity at - 2.
