Write a formula for quadratic function if its graph has the vertex at point (0,6) and passes through the point (−1,−2).

The formula of the quadratic function is

A quadratic function is represented as:

The vertex of the quadratic function is given as:

So, we have:

This gives:

The quadratic function passes through (-1,-2).

So, we have:

Subtract 6 from both sides

Substitute -8 for a in

Hence, the formula of the quadratic function is

y = - 8x² + 6

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (0, 6), thus

y = a(x - 0)² + 6, that is

y = ax² + 6

To find a substitute (- 1, - 2) into the equation

- 2 = a(- 1)² + 6, that is

- 2 = a + 6 ( subtract 6 from both sides )

- 8 = a

y = - 8x² + 6

b) 36

step-by-step explanation:

18 times 2 is 36

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.
