Answer 2

@amorfide last one, don't worry if you don't know it... Ill give you a medal anyway! Sorry

Answer 3

has money
h(x)=103

saving account s(x)=1.03x-1

already has h(x) as she starts with money at home (103)
she wants to use a savings account to gain interest s(x)
she can combine the function by depositing her money into an account, and gaining interest
this would mean depositing the function h(x) into s(x) which would give s(h(x))
s(h(x))=1.03(h(x))-1
s(h(x))=1.03(103)-1

Answer 4

this new function would give the amount of money in the savings accoutn after gaining interest
