James is building a house on the lot shown below. The dimensions of the lot are (6+x) feet and (6−x) feet. The blue prints show the dimensions of the house to be (2+x) feet and (2−x) feet. The rest of the lot will be his yard. How large is the yard?

  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.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

c. (3,2,6) is the answer.
