Question

Is the equation an example of growth or decay? y = 4x. Can you help me and show me how to do these cause my whole assignment is on this, and so is the quiz i have to take thank you

Answer 1

well if you put a number in (x = 1), you get a positive number (y = 4)

the next number (x = 2), gives you a higher positive number (y = 8)

good indication that it's growth

the pattern continues

x=3, y=12

so it's growth

decaying would be the opposite (input a number, output goes down)

Answer 2

so i can put any numberin for x?

Answer 3

ohhh i get it! now what would one look like if it was decaying ?

Answer 4

oh btw the eqution is actually y=4^x

Answer 5

yep

the function y= x (which is what y = 4x is )

has a domain of all real numbers, meaning any number can go in

and a range of all real numbers (any number can come out)

decay would be the opposite

x = 1, y = 4
x = 2, y = 0
x = 3, y = -4

for instance, that's one example

Answer 6

well that doesn't really make sense with y = 4x, but that sequence of numbers is decaying >_> lol

Answer 7

so it would be decaying then ?

Answer 8

you know what i think im just going to ask my teacher tomorrow, since there are also negatives and stuff, but thank you for the help!

Answer 9

well the answer to your original question was growth, but the pattern i just showed was decaying. and your welcome
