Which equation is y = â€""6x2 3x 2 rewritten in vertex form?.
Ber [7]

The vertex form needed is :

-6(x-0.25)^2 +2.375

Given the equation:

-6x^2 + 3x + 2\\

The vertex form of f(x) = ax^2 + b(x) + c is given by:

f(x) = a(x-h)^2 + k

Here, (h,k) is the vertex of the parabola equation given.

Conversion will go like this:

-6x^2 + 3x + 2\\= -6(x^2 - 0.5x) + 2\\= -6(x^2 -0.5x + 0.0625 - 0.0625) + 2\\= -6(x^2 -0.5x + 0.0625) + 2 +0.375\\= -6(x-0.25)^2 + 2.375\\\\

This is the resultant vertex form.

Thus the vertex form needed is :

-6(x-0.25)^2 +2.375

What is the equation of a circle with center (-4 2) and diameter 6?
ASHA 777 [7]

Use the general form:-

(x - a)^2 + (y - b)^2 = r^2 where (a, b) is the centre and r = radius

Here the radius = 1/2 * 6 = 3 so r^2 = 9 and we have the equation:-

(x + 4)^2 + (y - 2)^2 = 9 (answer)
