Hey all..so Ill go ahead and say that I recently discovered passion for math..I didnt really learn too much in highschool

when graphin y=-f(x)
-how would I input on ti83?

how do y=2f(x) differ from y=f(2x)
-when it comes to input and output..how would the outputs differ? Im basically lost in the "how to" for the output

ty!

how do y=2f(x) differ from y=f(2x)

Why not trying with an example ?

case f(x) = x^3 (cubic function)

try x=5 :
2f(x) = 2 (5^3) = 2(125) = 250
f(2x) = f(10) = 10^3 =1000
So 2f(x) differ from f(2x)

or try x=1 :
2f(x) = 2 (1^3) = 2
f(2x) = 2^3 = 8
