Question

Every week Annie plants 2 saplings in her garden. The function below shows the total number of saplings f(w) in her garden after w weeks

f(w)=2w+3

Which statement describes the y intercept of the graph of the function

It is equal to 3 and represents the orginal number of saplings in Annies garden

It is equal to 2 and represents the original number of saplings in Annies garden

It is equal to 3 and represents the number of saplings in Annies garden at the end of the first week

It is equal to 5 and represents the number of saplings in Annies garden at the end of the first week

Answer 1

Answer 2

The function is similar to the function f(x) = mx + b. What's the y-intercept of f(x) = mx + b?

Answer 3

Since the b is equal to 3 and when w=0, f(w)=3, that would mean there were 3 saplings there before Annie planted any saplings.

Answer 4

Do you see a statement that more or less says that?

Answer 5

The first one?

Answer 6

Bingo

Answer 7

So, that would be the answer?

Answer 8

Note the Easyaspie314 post, the 3 is equal to the b and would represent value of y when
x=0. Confidence is an important characteristic. Yes first choice is correct.

Answer 9

Ah, okay. Thanks!

Answer 10

After the first week there would be 5, after 2nd week there would be 7 and so on.

Answer 11

That makes sense. ^-^

Answer 12

Yes I think relating this to the slope intercept form of a line is the correct way to go.

Answer 13

Good luck with your studies, I must sign off now.

Answer 14

Oh, okay. Bye!
