Question

If h(x) = 6 – x, what is the value of ?

Answer 1

Well the notation means h(h(10)
so if we start with h(10) what do we get?

Answer 2

how am i supposed to know

Answer 3

@mathmale

Answer 4

well if h(x)=6-x and you are trying to find h(10), the x from the h(x) has been replaced by 10, so every time you see x, replace it with 10

Answer 5

still not following you

Answer 6

if h(x)=5+x and you are trying to find h(6) it means that where ever you see a x you change it for a 6, therefore,
h(x)=5+x
h(6)=5+6
now try and apply this to h(10) where h(x)=6-x

Answer 7

well i know ill still be in high school for a long time i still dont follow you

Answer 8

h(x) is just shorthand for a function
instead of writing y=6-x you can write h(x)=6-x
