Question

polynomial and rational functions
f(x)=x^4+x^3-7x^2-x+6
State the domain and range using interval notations
Domain:
Range:
Relative max (point):
Relative min (point):
x intercepts:
y intercepts:
end behavior:

Answer 1

no denominator ,no radical , no log , so domain is R

Answer 2

for finding range
first calculate f '
then f'=0
then check for the sign of f' in a table
so you will have max , min and range at the same time
