Answer:

The purple coupon

Step-by-step explanation:

so its pretty straightforward

the 50% off of 399.80 is about 200 dollars becuase you can use basic estimation and we know half of 400 is 200 so about 200 dollars and a little less becuase of that 20 cents

The $200 off on a purchase $350 or more is better becuase since its Exactly $200 dollars off so Nancy would’ve saved more since $200 is greater than half of 399,80 which is 199.90.

Answer:

3) all \: real \: numbers, (  - \infty , \infty ), or -  \infty  \leqslant x \leqslant  \infty (same thing)

4) -  \infty  < y < 0 or ( -  \infty ,0) (same thing)

5) -2 or (0, -2) (same thing)

Step-by-step explanation:

3) Domain represents the amount of x-values in a function. The image shows that the function's arrows point in both directions (right and left), infinitely, so the domain would be all \: real \: numbers, (  - \infty , \infty ), or -  \infty  \leqslant x \leqslant  \infty(same thing).

4) Range represents the amount of y-values in a function. The function goes downward forever (- \infty  < y) by the indication of an arrow and halts just under the y-axis (y < 0). After combining these two inequalities, you see that the range is -  \infty  < y < 0 or ( -  \infty ,0) (same thing).

5) The y-intercept is where the function crosses the y-axis. In this function, the y-intercept is -2 or (0, -2) (same thing).
