Question

At a grocery store, the number of customers arriving per hour is shown by the function f(x) = 2x + 1. Find the number of customers that arrived in the 6th hour.

Answer 1

So by the 6th hour, your x=6

Answer 2

Thank you very much

Answer 3

That wasn't the whole answer, btw??

Answer 4

What's your answer? :D

Answer 5

i am not sure how to get the answer acually

Answer 6

So f(x) is a function where x is the variable. In this scenario x is 6. Can you plug that into the function f(x) = 2x+1?

Answer 7

2(6)+1

Answer 8

Yep

Answer 9

f(6) = 2*6+1

Answer 10

which then equals 13, which is the answer to how many customers that have arrived.

Answer 11

Not so hard, eh?

Answer 12

so you multiply 6 by 2 then add 1

Answer 13

no not so bad thank you very much

Answer 14

That's right, there's a multiplication there that is left out when writing, that might make it unclear when it's new. It actually says f(x) = 2*x+1, and you just put in whatever x you want.

Answer 15

Glad I could help.

Answer 16

ok thank you so much you really helped me out
