All points of the step function f(x) are graphed.
what is the domain of f(x)?

{x|-4 {x|-3 {x|1 < x < 4}
{x|2 < x < 4}

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
