Question

9. Every day during January, Joshua ran two miles. Let x represent the date in January and f(x) represent the total number of miles Joshua had run by the end of that date.

f(1) = _____

Answer 1

Any ideas?

Answer 2

i thought that it was f(1) = 2x

Answer 3

f(1) is a particular number, 2x is a variable expression.

Answer 4

f(1) means how many miles has he run after 1 day.

Answer 5

so it would be 2? if f(x) = the total number of miles Joshua had ran by the end of that date.

Answer 6

Yes, f(1) = 2 miles.

Answer 7

ok so there was no equation involved then?

Answer 8

Correct.

Answer 9

ah Ok so that maybe the same for the others thank you :)

Answer 10

thanks for asking

Answer 11

I am not 100% sure but I think they may be expecting the following:
From " Let x represent the date in January and f(x) represent the total number of miles Joshua had run by the end of that date." we can conclude:
f(x) = 2x
Then, f(1) = 2 * 1 = 2.

Answer 12

that came to mind it is supposed to be a function

Answer 13

I forgot to include: "Every day during January, Joshua ran two miles."

Answer 14

Look at what the question asks for: f(1) = _____

Answer 15

f(2) = 4
f(3) = 6
f(4) = 8

Answer 16

so it would have to be f(2) = 2 x in order for f(2) = 4

Answer 17

just as if it was f(x) = 2 x
