Which point is an x-intercept of the quadratic function f(x) = (x + 6) (x-3)?
(0.6)
(0.-6)
(6.0)
(-6,0)
O

(6.0)

Step-by-step explanation:

Lets set f(x) aka y to 0 because you want a y intercept first

0 = (x+6)(x-3)

Now lets set each equal to 0 and solve

0 = x + 6

-6      -6

Now that we have what equals when y is 0 and it is corresponding to one of the answers you do not need to try the other. The answer is (-6,0)

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
