It looks like the parabola are going down, so the coefficient should be negative,
B or C,
then we see that the parabola has x -intercepts (1,0) and (5,0)
these roots should be written as multiples
x=1, so x-1=0
and
x=5, so x-5=0,
so (x-1)(x-5) and negative first coefficient -2 at the same time.
We can see only in the
B. <span>f(x) = –2(x – 5)(x – 1)</span>
Answer:
Biker 1: 20mph
Biker 2: 15mph
Step-by-step explanation:
Look at the x - axis bar thing at 1 hour, if you look up a little, you see 2 dots. Those are the dots for the mile per hour. You can see the blue dot is at 20 miles and the red one is at 15.
It looks like it may be 15 divided by 2.
