Question

For the function f(x) = x + 7, what is the ordered pair for the point on the graph when x = 2b
A. ( 2b, 2b+7)
B. ( 2b, x + 7)
C.( x, x + 7 )
D. (x, 2b + 7)

Answer 1

in the ordered pair the first value will be the value of x and the second value will be the value of f(x). u can get the value of f(x) by plugging the given value of x in f(x). Does that help?

Answer 2

Kinda but how do you get the value of x

Answer 3

It is given

Answer 4

so the answer is b.

Answer 5

nope. find the value of f(x) when x=2b

Answer 6

The pair looks like this (x;y) with y=f(x). Gues again

Answer 7

guess*

Answer 8

i am confused but is it answer d then

Answer 9

nope

Answer 10

what is the value of x given>

Answer 11

You replace x with 2b

Answer 12

You replace x with 2b on everything. There shouldn't be any x left in your final answer.

Answer 13

oh ok thanks

Answer 14

can you help me with one more

Answer 15

Ok

Answer 16

Btw what answer did you get for the first ?

Answer 17

Find the f(5)

f(1) = 2 and f(2) = 4, f(1) + f (2) +f(n-1), for n > 2
so f(5) =

Answer 18

i got for the first one A.

Answer 19

That's correct. Gz!

Answer 20

There's something wrong about this part f(1) + f (2) +f(n-1)

Answer 21

oh yeah before the f(1) there should have been a f(n)= so like 4,f(n) = f(1)

Answer 22

You should find f(3) and f(4) before you can find f(5).

You just replace n with 3 on this f(n) = f(1) + f (2) +f(n-1) and replace f(1) and f(2) with their respectives values.

Same for f(4).

Answer 23

D.

Answer 24

for the first one

Answer 25

well actually its A but thanks for answering

Answer 26

oh

Answer 27
