What is the end behavior of the function [tex]h(x) = 2(x-3)^2[/tex]?

As [tex]x[/tex] approaches negative infinity, [tex]h(x)[/tex] approaches [tex]$\square$[/tex]

As [tex]x[/tex] approaches positive infinity, [tex]h(x)[/tex] approaches [tex]$\square$[/tex]



Answer :

To determine the end behavior of the function [tex]\( h(x) = 2(x-3)^2 \)[/tex], let's analyze how [tex]\( h(x) \)[/tex] behaves as [tex]\( x \)[/tex] approaches both negative infinity and positive infinity.

1. As [tex]\( x \)[/tex] approaches negative infinity:

Consider the term [tex]\( (x-3)^2 \)[/tex]. As [tex]\( x \)[/tex] becomes very large in the negative direction (i.e., as [tex]\( x \)[/tex] approaches negative infinity), the term [tex]\( (x-3) \)[/tex] will also be a large negative number. However, when this term is squared, it becomes a large positive number since squaring a number always results in a non-negative value.

Therefore, as [tex]\( x \)[/tex] approaches negative infinity, [tex]\( (x-3)^2 \)[/tex] becomes very large. Multiplying this large positive value by 2 does not change the fact that it is large and positive. Hence, when [tex]\( x \)[/tex] approaches negative infinity, the value of [tex]\( h(x) \)[/tex] will increase without bound.

Therefore, as [tex]\( x \)[/tex] approaches negative infinity, [tex]\( h(x) \)[/tex] approaches positive infinity.

2. As [tex]\( x \)[/tex] approaches positive infinity:

Similarly, as [tex]\( x \)[/tex] becomes very large in the positive direction (i.e., as [tex]\( x \)[/tex] approaches positive infinity), the term [tex]\( (x-3) \)[/tex] will also be a large positive number. Squaring this positive number will result in a large positive value.

Therefore, as [tex]\( x \)[/tex] approaches positive infinity, [tex]\( (x-3)^2 \)[/tex] also becomes very large. Multiplying this large positive value by 2 similarly results in a larger positive value. Hence, as [tex]\( x \)[/tex] approaches positive infinity, the value of [tex]\( h(x) \)[/tex] will also increase without bound.

Therefore, as [tex]\( x \)[/tex] approaches positive infinity, [tex]\( h(x) \)[/tex] approaches positive infinity.

Based on this analysis, the correct answers are:

- As [tex]\( x \)[/tex] approaches negative infinity, [tex]\( h(x) \)[/tex] approaches positive infinity.
- As [tex]\( x \)[/tex] approaches positive infinity, [tex]\( h(x) \)[/tex] approaches positive infinity.
