What do the graphs of the two even degree functions (y = x^2 and y = x^4) have in common?

We have been given two functions and .

Now questions is asking about what do the graphs of the two even degree functions and have in common.

By property of even edgree polynomial we know that if it starts from top then it will also end at the top.

If it starts from bottom then it will also end in bottom.

In simple words, we can says that even degree polynomial starts and ends in same direction.

Given functions and are also even degree polynomial so common thing about them is that they will start and end in the same direction. (Upward). You can also check the attached graph of both for better guidance.

step-by-step explanation:

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
