Question:Adding finctions values and plot issue

Hello,

I have two functions:

Gx(x)=0.025+(x^2)/40

Hxi(x)=0.006+0.5*x^2

with values I'd like to add

Fx(x)=Gx(x)+Hxi(x)

and plot new function

I use

F=plot(Fx(x),x=0..2)

G=plot(Gx(x),x=0..2)

H=plot(Hxi(x),x=0..2)

then:

display(F,G,H)

But it doesnt work. Then when I displaed

By the way, Hxi are correction, in function of x.

 

The second problem with I have is with ploting.

Gx is quadratic function and on plot it looks like U, but this function is commonly represented rotated clockwise by 90deg so it looks like C. How can plot rotated it and find a line going thrugh (0.0) and tangent to Fx in highest point.

Thanks in advance for your help.
