Write the vertex form of the equation of the parabola which has a vertex of (0, 0) and contains the point (2, –2).

1 answer:

5 0

Hello:
an equation is : f(x) = a(x-0)² +0
the point (2 , -2)in parabola : -2= a(2-0)² +0
-2=4a
a =-1/2 is the coefficient of the squared expression in the parabola equation
the vertex form is m f(x) = -1/2x²

Let point R be (x₁, y₁) and Point S(10, 10) be (x₂, y₂)

Midpoint is given by $( \frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

We know that the midpoint is (9, 8)
We will use this to evaluate the value of (x₁, y₁)

$\frac{x_1+x_2}{2}=9$
$\frac{x_1+10}{2}=9$
$x_1+10=18$
$x_1=8$

$\frac{y_1+y_2}{2}=8$
$\frac{y_1+10}{2}=8$
$y_1+10=16$
$y_1=6$

Point R (x₁, y₁) = (8, 6)
