APPC 1.7B video check

When evaluating a rational function for inputs of very large magnitude, what happens to the constant terms and terms with lower powers of the variable?

• They become the most influential parts of the function.

• They cause the function to become undefined.

• They become insignificant and approach zero.

• They lead to an oscillating behavior of the function.

For a rational function, if the degree of the polynomial in the denominator is greater than the degree of the polynomial in the numerator, what is the end behavior of the function as x approaches positive or negative infinity?

• The function's value approaches positive or negative infinity.

• The function's value approaches zero.

• The function's value approaches a non-zero constant.

• The function's value oscillates.
