The Manga Guide to Calculus

10 Prologue

In this case, f

exprees the

relationship

or rule

betwn

“a parent”

and “an

ospring.”

And this

relationship is

true of almost

any animal. If x

is a bird, y is a

chick.

Okay! Now

lk at this.

For example,

the relationship

betwn incomes

and expenditures

can be sn as a

function.

Like how when

the sales at a

company go up,

the employs

getbonuses?

The spd of sound

and the temperature

can also be expreed

as a function. When

the temperature goes

up by 1°C, the spd

of sound goes up by

0.6 meters/second.

And the

temperature in the

mountains goes

down by about

0.5°C each time you

go up 100 meters,

doesn’t it?
