For the polynomialf(x)=-2x^3-2x^2+7x-25 as x -> -∞, f(x) -> ∞truefalse

True

Step-by-step explanation:

By definition for a function of the form:

It is true that if and n is odd then:

In this case

Therefore

and → odd number

Then

This means that when

The statement  x -> -∞, f(x) -> ∞  is True

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
