Which quadratic equation models the situation
correctly?
y = 27(x – 7)2 + 105
y = 27(x - 105)2 +7
y = 0.0018(x – 7)2 + 105
y = 0.0018(x - 105)2 + 7

Which quadratic equation models the situation correctly y 27x 72 105 y 27x 1052 7 y 00018x 72 105 y 00018x 1052 7 class=

Answer:

  y = 0.0018(x -105)² +7

Step-by-step explanation:

The vertex of the function is at (x, y) = (105, 7), so the equation will be of the form ...

  y = a(x -105)² +7

We can use x=0 to find the value of "a". At x=0, y=27, so ...

  27 = a(0 -105)² +7

  20 = 11025a

  20/11025 = a ≈ 0.0018

So, the model is ...

  y = 0.0018(x -105)² +7
