Fill in the missing word: an unknown or changeable quantity is called a(n)

add a pic of the graph, then ill edit this "answer" and solve it for you : 3

step-by-step explanation:

d is ur answer hopes this i dont really know how to explain it to u.

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.
