If a female baby weighs 20 pounds at 1 year , what do u predict she will weigh 30 year of age?

600 pounds

Step-by-step explanation:

A baby weighs 20 pounds at 1 year

At 30 years old, she will weigh 20 pounds × 30

= 600 pounds.

  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.
