write the equation for the following graph (-5,-8),(0,-5),(0,8)

Question

anonymous · Answer

does anyone know what this means?

ganeshie8 · Answer

think of it like this :
1) between (-5, 0) it has a slope of 3/5
2) at 0 its value is 8

can you write equation now ?

anonymous · Answer

That is not a line, I think.
It may be
$$
x=-\frac{5 y^2}{48}+\frac{5
   y}{16}+\frac{25}{6}
$$
Stay tuned to explain it to you.

anonymous · Answer

huh?

anonymous · Answer

You write
$$
f[y] = a y^2 + b y + c\
f[-8] = -5 \ f[-5] = 0 \ f[8] = 0
$$
and you solve the three equations for a, b and c

anonymous · Answer

you get
$$
\begin{array}{ccc}
 a=-\frac{5}{48}, &
   b=\frac{5}{16}, &
   c=\frac{25}{6} \
\end{array}

$$

There is no one line going through the three points. There is a parabola. This is the one I found above.

ganeshie8 · Answer

this is just a line & a point
1)  y+8 = (3/5)(x+5)    {-5<= x < 0}
2) y = 8   {x = 0}

anonymous · Answer

ok I got what you are saying im trying to look now and make sure i wrote this question down correct.

anonymous · Answer

If the question is ti find one equation to fit the three points, then it is a parabola
The one I found.

anonymous · Answer

See the graph going through your red points.

Did you see the graph?
