By comparing the perimeters, we can deduce the scaling factor:

k = \dfrac{34}{20} = 1.7

The areas scale with the square of the scaling factor, so the new area is

19.6 \cdot 1.7^2 = 56.644

Answer:

f(x) = 6x² - 24x + 21

Step-by-step explanation:

The equation of a quadratic function in vertex form is

f(x) = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k ) = (2, - 3 ) , then

f(x) = a(x - 2)² - 3

To find a substitute (1, 3 ) into the equation

3 = 1(1 - 2)² - 3

3 = a(- 1)² - 3

3 = a - 3 ( add 3 to both sides )

6 = a

f(x) = 6(x - 2)² - 3 ← in vertex form

     = 6(x² - 4x + 4) - 3

     = 6x² - 24x + 24 - 3

f(x) = 6x² - 24x + 21 ← in standard form
