Write the equation of a parabola that has a vertex of (-2,5.5) and passes through the point (-2.5,2.5).

vekshin1

The equation of a parabola that has a vertex of (-2, 5.5) and passes through the point (-2.5, 2.5) is $y=-12(x+2)^2+5.5$

The vertex form of the equation of a parabola is:

$y=a(x-h)^2+k$

where (h, k) is the vertex of the parabola

(x, y) is the point that the parabola passes through

The vertex, (h, k) = (-2, 5.5)

The point, (x, y) = (-2.5, 2.5)

Substitute h = -2, k = 5.5, x = -2.5, and y = 2.5 into the equation to solve for a.

$2.5=a(-2.5-(-2))^2+5.5\\\\2.5=a(-2.5+2)^2+5.5\\\\2.5-5.5=a(-2.5+2)^2\\\\-3=a(-0.5)^2\\\\-3=0.25a\\\\a = \frac{-3}{0.25} \\\\a = -12$

Therefore, the equation of the parabola is:

$y=-12(x-(-2))^2+5.5\\\\y=-12(x+2)^2+5.5$

Two students in your class, Tucker and Karly, are disputing a function. Tucker says that for the function, between x = -3 and x

trasher [3.6K]

This can occur through a parabola that has zeroes at x = 3 and x = -3. There is no rate of change because the y values do not change at those points because they are both 0. Karly can be correct because that turning point can be a vertex of a parabola. The parabola's function would increase until it reaches it's highest point and then go back down again. In this way, Karly and Tucker can both be correct.

Hope this helps :)

To calculate mean you add up all the numbers you have, then divide it by the total pieces of data, for example: 2 4 3 1 = 2+4+3+1=10 10÷4=2.5

To calculate median, you find the middle number, it helps to put the numbers in order. If there are two middle numbers, add them up and divide by 2.

To calculate mode, you find the number that appears the most.

Comment if you want the answers.
