this is an easy question. there are 2 ways to do it by the definition or by using the differnation rules.

Definition

1 write the expressions for f(x) and f(x+h)
2 expand and simplify the difference quotient
f(x+h)- f(x)/ h
3 using the simplified quotient, find f `(x) by evaluation the limit
f `(x)=lim f(x+h)- f(x)/ h
h->0

power rule
d/dx x^n=nx^n-1

so we use the power rule less work. since u have a choice. we us the power rule

so d/dx 2x+3= 2

ps 3 is a consant. derative of a constant is d/dx c=0
so it would be like 2+0=2

see i told you this was an easy question
