What is the limiting value of a function?</h3>
Limiting Value of a Function. The function's limit is the value of the function as its independent variable, such as x approaches a certain value called the limiting value. For simple equations, this is similar to finding out the value of y when x has a unique value.
Given that,
f(x) =
First to calculate the limit value of the given function at x=0.
=
= 4×0×1 (∵ cos0 = 1)
= 0
Similarly,
=
= 4××cos
= 4×× (∵cos60° = )
= 1.153
Hence, The value of the and are 0 and 1.153.

Answer:
He did not check for extraneous solutions.
Step-by-step explanation:
He solved the equation correctly and obtained solutions -2 and -5, but there is one final step he did not do.
Every time you square both sides of an equation to solve it, you must check for extraneous solutions. If he did, he would have eliminated x = -5.
Answer: He did not check for extraneous solutions.

Each year, the premium is multiplied by (1 - 0.04) = 0.96. After 19 years, the premium will be the original value multiplied by 0.96^19.
113.00*0.96^19 ≈ 52.03
Your premium is expected to be $52.03 each month.
