Answer:
B
Step-by-step explanation:
choices are:
A. y=11.41x2+154.42x−143.9
B. y=−11.41x2+154.42x−143.9
C. y=11.41x2+154.42x+143.9
D. y=−11.41x2+154.42x+143.9
substitute x=1
A. y=11.41+154.42−143.9 =~25
B. y=−11.41+154.42−143.9 =~0
C. y=11.41+154.42+143.9 =~310
D. y=−11.41+154.42+143.9 =~290
C n D are way off n cannot be right.
substitute x=5 in A n B
A: y=11.41(5)^2+154.42(5)−143.9= ~913
B: y=−11.41(5)^2+154.42(5)−143.9
= ~343
so ans is B
