for the polynomial

f(x)=1-2x+5x⁴

as
x→∞,f(x)→-∞

a. true
b. false

As x gets sufficiently large the term that is going to "win out" is the highest power term (with respect to a polynomial) so that means the 5x^4 term will grow largest, it is positive so that means it should go to POSITIVE infinity.

Answer 2

b. false that is.
