Question

Hi, I just glitched in these two question about functions, thank you so much if you answer (or tried to)!

10. In the figure, in Cartesian frame xOy, the graphs of two functions f and g are represented.

It is known that the function f is defined by f(x) = x²/2; g is an inverse proportionality function; point A belongs to the graphs of functions f and g; the point B of abscissa 6 and ordinate b belongs to the graph of g.

10.1. Write the algebraic expression of the function g and determine the value of b.

10.2. Determines the algebraic expression of a direct proportionality function whose graph contains point A. (everything has been translated)

Answer 1

i think the function of g i can sort of tell that it is a right angle sort of. whoch a right angle is 90 *? and the value of b might be an obtuse angle which i think is equal to 180*? but im not for certain... im sorry i thought this would be easier than i thought but i tryed, i havent learned that yet but were learning degrees. maybe the function of g is up 6 over 5? and b would be up 5 over 6? sorry if thats confusing i tryed to understand it. after i saw the picture a second time i saw a graph so thats why i said up 5 over 6 or up 6 over 5

sorry thought, i thought it might be easier than i thought but i understand what you mean now. its confusing a bit...

i hope you get someone to give you a much better anwser than i did, and have a great day!
