Answer:
<h2>Function is y = x.</h2><h2>Domain:Step-by-step explanation:
In the given image, the line passes through (-1, -1) and (1, 1).
Let the equation of the line is , where m is the tangent of the line and c is a constant.
Putting the co-ordinates of the points in the equation, we get and
From the two equations we get, c = 0 and m = 1.
Hence, the function is y = x.
Domain is .
Range is
Answer:
Change per week: $20
Starting amount of money: $550
Step-by-step explanation:
<u>Given equation</u>:
where:
<u>Change per week</u>
As the variable x represents the number of weeks, its coefficient represents the change per week in the amount of money.
Therefore, the change per week in the amount of money in the account is $20.
<u>Initial Balance</u>
The starting amount of money in the account (initial balance) will be the value of y when x = 0:
Therefore, the starting amount of money in the account is $550.
