For each of the functions below, describe the domain of definition that is understood: f(z) = (1/x²)+1
Answers
Answer: x 0
Step-by-step explanation:
The domain of a function consists of the x-values that have a y-value in a function. The +1 shifts the graph upwards 1 unit. This only affects the range, the y-values. The x is in the denominator of a function, and the denominator of a function can never be 0, so we can say x 0. There are no other restrictions on the domain; x can be negative, x can be positive, but x cannot be 0.
If we graph this function, we'll see that there are no y-values when x = 0. We say that there is a vertical asymptote at x = 0, an imaginary line at an x-value that does not have any y-values.
I hope this helps! :)

Two different websites offer the same watch for sale. The watch costs $45 on both sites. The site, Watches for Less charges a shipping fee of 4% of the cost of the watch. The site, Tick Tock charges 2.5% of the cost of the watch for shipping. How much less will the total cost of the watch be if purchased from Tick Tock?

Answer:
$0.67
Step-by-step explanation:
Cost of Watch on both sites=$45
Watches for Less charges a shipping fee of 4% of the cost of the watch.
Therefore, total cost of the watch at Watches for Less
=$45+(4% of 45)=45+(0.04 X 45)
=45+1.8
=$46.8
Tick Tock charges 2.5% of the cost of the watch for shipping.
Therefore, total cost of the watch at Tick Tock
=$45+(2.5% of 45)=(45+0.025X45)
=45+1.13
=$46.13
Difference In Cost
Cost at Watches for Less-Cost at Tick Tock
=$46.8-46.13
=$0.67
The total cost of the watch will be $0.67 less if purchased from Tick Tock
