Question

I'm confused on functions...if f(x)=2x+1, what is f(t+1) ?

Answer 1

f(x) = f(t+1)
it means that x = t+1

Answer 2

so for your function f(x) = 2x+1
and we're asked f(t+1). that means that our x = t+1. So just plug that into our function

f(t+1) = 2(t+1)+1
and solve

Answer 3

ohhh so is it okay to still have a variable, in this case t, in the solution?

Answer 4

yup

Answer 5

so just solve this part
2(t+1)+1 and that will be our f(t+1)

Answer 6

distribute the 2 for (t+1)
2(t)+2(1)+1
and combine like terms/simplify

Answer 7

what's 2+1 ?

Answer 8

=2t+3 ?

Answer 9

correct
