The zeros of a quadratic function are 4 and 8. What is the axis of symmetry of the function?

1 answer:

3 0

So if you want to have a factored form...

If the zeroes are +4 and +8, you would write
(X-4) (x-8)
Then you would multiply it out to get to quadratic form...

So, (x-4)*(x-8)
X^2 - 12x + 32

Then you would plug it into the formula for axis of symmetry...
X= -b/2a

X=12/2 = 6

X=6
