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

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
