Answer:
negative infinity
Step-by-step explanation:
f(x) = 3 x^7
As x approaches - infinity we do not care about the 3 since it is positive
f(-inf) = (- inf)^7
We can take the negative out since it is to a negative power
f(-inf) = - (inf)^7
inf raised to a power is still infinity
F(-inf) = - inf
It will approach negative infinity
