A tectonic plate in Earth's crust moves at a constant rate of 4 centimeters per year. In a
different part of the world, another tectonic
plate moves at a constant rate of 30
centimeters in ten years.
Is this or is it not a proportional relationship if so why?

i will take them

step-by-step explanation:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

i hope this you : d

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
