Using the function below, answer the questions.

f(x)=-3x^9 +30x^6 -21x^5 + 30x^4 + 18x^3 - 16x^2 +21x -7

What is the degree of the function? _________

What is the leading coeffiecient? _________

What is the maximum number of x intercepts of f(x)? _________

What is the maximum number of turning points for f(x)? _______

What is the y intercept? ___________

End Behavior: x ----> - inf. f(x) ----> _________ x------> inf. f(x) ---> _________

What are the possible rational zeros of the function?

Explanation / Answer

Degree

Degree is the highest exponent which is 9 .

Leading coefficient

Leading coefficient is the constant that is with the term which have degree. Which is -3 here

Maximum number of x intercept = degree=9

maximum turning points= degree-1=9-1=8

y intercept, x=0

f(x)=0+0-0+0+0-0+0_7=-7

Since the degree is 9 which is odd and leading coefficient is -3 which is negative

Therefore

asx-----> -infinity, f(x)----->infinity

x-------->infinity, f(x)-------->-infinity
