Number of seconds Height (in feet)

0

11

1

13

2

13

Answer 1

Answer: i forget but it's like the one that ends in 10.164 or something like that

Explanation:

Answer 2

`y=-x^2+3x+11`

Explanation:

The given data table is

Number of seconds : 0 1 2

Height (in feet) : 11 13 13

We need to find quadratic regression equation that fits these data.

The general form of quadratic regression equation is

`y=ax^2+bx+c` .... (1)

Using the graphing calculator we get

a = -1 , b = 3 and c=11

Substitute these values in equation (1), to find the quadratic regression equation that fits these data.

`y=(-1)x^2+(3)x+(11)`

`y=-x^2+3x+11`

Therefore, the quadratic regression equation that fits the data is
`y=-x^2+3x+11`.
