Write the equation of the parabola in vertex form that has the following properties: passes through the point (2, 12) and has a
tatuchka [14]

Answer:

<h3>              f(x) = 4(x - 4)² - 4  </h3>

Step-by-step explanation:

f(x) = a(x - h)² + k           - vertex form of the equation of the parabola with vertex (h, k)

so the equation of parabola with the vertex (4, -4) is

f(x) = a(x - 4)² - 4  

passes through the point (2, 12)  means if x=2 then f(x)=12

12 = a(2 - 4)² - 4  

12 +4 = a(-2)² - 4 +4

16 = 4a

a = 4

Therefore the equation (in vertex form) of parabla is:

                                 <u> f(x) = 4(x - 4)² - 4  </u>
