x < 0

Step-by-step explanation:

If you look at the values of y, they get bigger ( less negative)  when x is negative, when x is positive they get smaller

The function is increasing when x<0

the perimeter is increased by a factor of 2

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
