Use the formula for finding axis of symmetry:
-b -25 -25
x = ------ ⇒ --------- = -------- = 2.6
2a 2(-4.9) -9.8
Yes, (x - 3) is a factor of the given polynomial.
If (x - 3) was a factor of the polynomial, then 3 would be one of the zeros of the function. That means if you input 3 into the function, you will get an output of zero.
In this case, inputting 3 does produce 0. Therefore, it is a factor.

So, to find our x-intercepts, y must be zero

ANSWER: (0,0) (-5.0) (9,0) are your x-intercepts
1 = 90
2 = 65
3 = 65
4 = 25
90+25=115
180-115=65
have a merry christmas :)
