I don't understand graphed equations

[vast knoll]

dyk what f(x) = x^2 looks like

[steep violet]

a slope

[vast knoll]

learn it from khan academy or organic chemistry tutor

[vast knoll]

what does -2 do to it

[steep violet]

not really sure

[vast knoll]

open up desmos and type this in: f(x) = x^2 - a

then click add slider a

and watch what happend as you move the slider

[steep violet]

ok it move down or up

[vast knoll]

wdym

[steep violet]

the center where the two lines intersect

it goes further up or further down

[vast knoll]

yea the entire thing gets shifted up or down

up if a > 0 and down if a<0

in general any constant shifts the function up or down

y = x + 2

the +2 shifts the line up by 2 units

same with x^2

the +2 shifts it up by 2 units

[steep violet]

what is f and x mean

[vast knoll]

f is a function of x

where x is the input

you input a number in

do a process to it

and get a number out

[steep violet]

ok thanks i think i understnad it now

[vast knoll]

f(x) = x + 1

x is the input

x + 1 is the process

and f(x) is the output

[vast knoll]

alr nice

you're welcome
