get a "feel" for the numbers.
for large values of x, isn't the first term "hugely negative" ?
for large negative values of x, isn't the first term 'hugely positive' ?
so where does the graph tend to go ?
Aren't both terms negative? I was going to say the answer was
B. Upward to the left and downward to the right
but you make it sound like
A.Downward to the left and upward to the right
read my reply again
try x = 10 and x = -10 (values which arent' even "large")
the term that dominates is -2x^5
for x=10, x^5 = 100000
and -2x^5 = -200000
if x=-10, -2x^5 = =2(-100000) = +200000
so what does the graph do?
You are right, it goes upward to the left and downward to the right, as I also suggested in my first reply.
