Would a horizontal line, a straight slanted line, a curve, or a jagged curve best represent the calories you burn during the day?

a jagged curve

Step-by-step explanation:

The number of calories you burn varies throughout the day, increasing and decreasing. A jagged curve represents increases and decreases over time.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
