Why are all sequences descrete in math

1 answer:

3 0

Answer:

If you collect all the terms of the sequence into a set, that set will always be discrete, because there's only countably many of them, and every interval is uncountable. So you could move outside of natural numbers to real numbers, but then it's no longer a sequence, it's just a function.

Which function below is the inverse of f(x)= 3x+5/7

Ipatiy [6.2K]

Inverse
replace f(x) wih y
solve for x
replace x with f⁻¹(x) and y with x

so

f(x)=3x+5/7
replace
y=3x+5/7
solve for x
minnus 5/7 both sides
y-5/7=3x
divide both sides by 3
$\frac{y- \frac{5}{7} }{3}$ =x
replace with f⁻¹(x)

f⁻¹(x)= $\frac{y- \frac{5}{7} }{3}$
