Tangent to x-axis = negative double root
2 positive real roots
Look at the graph.
We've already stated the real zeros. That would leave 2 complex zeros if the degree were 6.
No. There are 3 direction changes in the graph. This is an even function.
Greetings all,
Have a hard time with a homework question with this graph:
The problem states: Consider the section of the function shown below.
a) How many distinct (different) real zeros does the function have? ___
b) Approximate their values. _____
c) If the degree of the function is known to be 6, then state how many real zeros and how many complex zeros it would have.
Complex zeros. _____
Real Zeros. _____
d) Is it possible that this is a portion of a 7th degree function? why?
That is a lot of question that I am baffled on. Some direction or steps would be great if possible.
