How can i find gx

ruby mountain
#

I dont speak this

#

I dont know the question

rare minnow
#

In question 1 they want me to say what the function g(x) is based on the picture

#

But idk how

#

And they want me to find h(x)

ruby mountain
#

Ok

#

So it looks like there is this function n

#

K and h are vectors?

rare minnow
#

No k and h are linear functions

#

And g is parabol

#

And i need to find gx

ruby mountain
#

What is n?

rare minnow
#

Also a function

ruby mountain
#

You can say g equals k and h at y=1

#

So if you know slope of k and h then you can fine the x value for g that equals 1

rare minnow
#

Ah

#

And what is h?

ruby mountain
#

And you solve a system of equations g(x_k)=1 and g(x_h)=1 where g(x)=ax^2+bx+c

rare minnow
#

Is it -1/2x +2 ?

#

Ok

ruby mountain
#

Their equations can be found doing point slope form for (-2,0) and (2,0) it looks like

rare minnow
#

Ok ty

ruby mountain
#

Also you know for ax^2+bx+c has b=0 since -b/2a=0

#

So you are really only solving for a and c

#

Visually c looks to be 5

#

So you can solve for a in -ax^2+5=1 for x=5

rare minnow
#

Okay thank you

ruby mountain
#

Ok the slope is 1/2 i think
