Question

What is the value of the function when x = 2?

Answer 1

horizontal flat line in that graph is called x axis

Answer 2

do you see points scattered over the coordinate plane ?
they represent the function

Answer 3

yes

Answer 4

Notice there is a point above each integer value of x

Answer 5

when x = 1, the point is `2` units above x axis so the value of function at x=1 is `2`

Answer 6

can you find out high high the point is above x=2 ?

Answer 7

so x=1 is the answer?

Answer 8

hey no, do you see any point above the x=2 ?

Answer 9

no:(

Answer 10

oh sorry:)

Answer 11

there is a point shown above x=2 :

Answer 12

how high above the x axis is that point located ?

Answer 13

think of x axis (flat horizontal line) as ground floor if it helps

Answer 14

6

Answer 15

that point above x=2 seems to be in 6th floor, yes ?

Answer 16

Right! so the value of function at x=2 is 6

Answer 17

thxs:)

Answer 18

thats your answer, we're done.
let me ask you a question

Answer 19

u so sweet!!!!!!!!!!

Answer 20

what is the value of function at x=3 ?

Answer 21

more work for you :) see if you can answer that

Answer 22

y = 4

Answer 23

Excellent! you're the master of coordinate plane !!

Answer 24
