A function has the ordered pairs (1,3), (7,4), (8,6), and (9,y). What restrictions are there on the value of y so that the inverse of the function is also a function? Explain.

  y cannot be 3, 4, or 6

Step-by-step explanation:

If the function is to have an inverse, the y-values cannot be repeated. This means ...

  y ∉ {3, 4, 6}

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
