Answer:
Let y = f(x) be a function with an independent variable x and a dependent variable y.
If a function f provides a way to successfully produce a single value y using for that purpose a value for x then that
chosen x-value is said to belong to the domain of f. If there is a requirement that a y-value produced by a function
must be a real number, the following conditions are commonly checked:
1. Denominators cannot equal 0.
2. Radicands (expressions under a radical symbol) of even roots (square roots, etc)
cannot have a negative value.
3. Logarithms can only be taken of positive values.
4. In word problems physical or other real-life restrictions might be imposed, e.g. time is
nonnegative, number of items is a nonnegative integer, etc.
Answer:
Calculating total cost.Multiply the cost of the item or service by the sales tax in order to find out the total cost.The equation looks like this:Item or service cost x sales tax (in decimal form) = total sales tax.Add the total sales tax to the item or service cost to get your total cost.

Answer:
for #1: 70x = y
for #2: 70x + 100 = y
Step-by-step explanation:
you pay $70 for x amount of time with will equal your total therefore it's 70x = y
if you have to pay a one-time fee of $100.00 then you have to add that to your equation giving you 70x + 100 = y
hope this is right
hope it helps too :)
Since decimals have places in 10 100 and 1000 you need a denominator with those number but since you already have a 10 you take the 7 and add a 0. in front so the answer is 0.7
Answer:
in a graph the x value at the y intercept is 0
is a typical decay function
if x = 0 thus = 1
so at 0 the function value would be A
