The graph of a function f is shown below. Use the zeros and the turning points of the graph to find the rule for f. A.
f(x) = x4 − 8x2 + 16

B. f(x) = −x4 + 5x2 − 4

C. f(x) = x3 + x2 − 4x + 4

D. f(x) = x4 − 5x2 + 4

Answer is D

Step-by-step explanation:

Using the zeros of the graph we should have y=0 when we put x=-2, x=-1, x=1, x=2

Only the function on option D works, so the answer is D

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
