Vertex (0,1) x intercepts is - 1 and 1 what is the equation of the parabola?
MrRa [10]
\bf y=a(x-{{ h}})^2+{{ k}}\\
x=a(y-{{ k}})^2+{{ h}}\qquad\qquad  vertex\ ({{ h}},{{ k}})

those are the vertex form of a parabola... so hmmm
the vertex of this one is at 0,1 and intercepts or "solutions" are at -1 and 1, so is opening downwards, notice the picture below

that means, the squared variable is the "x", thus the form is \bf y=a(x-{{ h}})^2+{{ k}}

now, we know the vertex is at 0,1, and two x-intercepts of \pm 1,0

thus      \bf y=a(x-{{ h}})^2+{{ k}}\qquad 
\begin{cases}
h=0\\
k=1\\
when
\\
x=\pm 1\\
y=0
\end{cases}
\\\\\\
\textit{so.. hmmm let us use the point ... say hmmm 1,0}
\\\\
y=a(x-{{ h}})^2+{{ k}}\implies 0=a(1-0)^2+1

solve for "a", to see what that coefficient is, then plug it back in the vertex form equation

the height of a desk is 11 inches shorter than the height of a chair. Write and solve an equation to find the height of the desk
Nostrana [21]

d=c-11

Step-by-step explanation:

d is desk

c is chair

The height of the d (desk) is always going to be 11 inches shorter than the chair. So subtract 11 from c (chair) and you will find d  (desk).

If the chair is 13 inches....

d=13-11

d=2

If the chair is 32

d=32-11

d=21

This equation will work with numerous numbers to find the size of the desk. If you want you can find the height of the chair as well!
