Question

Consider the leading term of the polynomial function. What is the end behavior of the graph?
-3x5 + 9x4 + 5x3 + 3
a. The leading term is -3x5. Since n is odd and a is negative the end behavior is up and up
b. The leading term is -3x5. Since n is odd and a is negative the end behavior is down and down
c. The leading term is -3x5. Since n is odd and a is negative the end behavior is up and down
d. The leading term is -3x5. Since n is odd and a is negative the end behavior is down and up

Answer 1

pos./neg. coefficient and even/odd power of the leading term

Answer 2

That makes more sense than the actual answers o.o

Answer 3

the first term is -3x^5 ?

Answer 4

Yes

Answer 5

you can also try some huge values of x to find the end behavior

Answer 6

\[-3x ^{5}+9x ^{4}+5x ^{3}+3\]

Answer 7

- <----- and -----> +

Answer 8

what answer do you get?

Answer 9

D?

Answer 10

C, up and down

Answer 11

Ah ok .. I was trying to figure it out between C and D and I guess I got the two reversed

Answer 12

since the power is odd, any positive x gives a positive number, but a neg. x gives you a negative number.. but it is multiplyed by -3
