Question

Complete the statements about the key features of the graph of f(x) = x5 – 9x3. As x goes to negative infinity, f(x) goes to infinity, and as x goes to positive infinity, f(x) goes to infinity.

Answer 1

Answer:

Negative and then positive

hope this helps!

Answer 2

Subsitute to find out
actually, since it is odd degree and positive leading coefient, it goes from bottom left to top right

so as x goes to negative infinty, f(x) goes to negative inifnty
as x goes to positive inifnty, f(x) goes to positive inifnty
