What is the frequency for each one

ok thats very interesting

0lz try yourself sorry for not answering

add them

step-by-step explanation:

idk you did not give the options or numbers so you cant solve it

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
