Question

MEDAL AND FAN PROMISED!!! PLZ HELP!!!

Answer 1

f(x) = 2(3)x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3

Answer 2

can you help me find the rate of change @kiamousekia

Answer 3

\(\large\color{black}{f(x)=2(3)^x}\)

Like this?

Answer 4

yes

Answer 5

\i need to find the rage of change

Answer 6

with that formula

Answer 7

@kiamousekia can u help me plz

Answer 8

How would you normally find the slope between the slope between points
\(\large\color{black}{(a,b)}\) and \(\large\color{black}{(c,d)}\) ?

\(\large\color{black}{m=\dfrac{b-d}{a-c}}\)

Answer 9

For section A, you need to find f(0) and f(1),
and then the slope between (0,f(0)) and (1,f(1)).

Answer 10

well i need 2 Find the average rate of change of each section.

Answer 11

so ik that formula

Answer 12

but i need help doing it

Answer 13

ok, and tell me what is f(0)=? and f(1)=?

Answer 14

(0,1)?

Answer 15

\(\large\color{black}{f(x)=2(3)^x}\)

\(\large\color{black}{f(0)=2(3)^0=?}\)
\(\large\color{black}{f(1)=2(3)^1=?}\)

Answer 16

(anything raised to power 0, is 1)

Answer 17

so i need 2 answer that equasion

Answer 18

Idk sorry

Answer 19

yes, you need to answer my 2 last questions
(those are your y-values of the 2 points, respectively)

and then use the slope formula

Answer 20

f(x) = 2(3)x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3
this is what im asking tho i need to find them sepretly

Answer 21

I know.

Answer 22

You have to know the y-coordinates of the 2 points to find the slope, don't you?

Answer 23

ok ok i got it now

Answer 24

What is the y-coordinate when x=0?
What is the y-coordinate when x=1?

Answer 25

(recall that your function is \(\large\color{black}{f(x)=2(3)^x}\) )

Answer 26

plug in 0 for x, and then plug in 1 for x.

Answer 27

so its 6 and there are no soulutions 2 the first 1

Answer 28

\(\large\color{black}{f(x)=2(3)^x}\)
\(\large\color{black}{f(0)=2(3)^0=2\cdot1=2}\)

So the y-coordinate when x=0, is y=2

Answer 29

Can you find the y-value when x=1? (do it same way I have done it)

Answer 30

im so confused

Answer 31

and im so sorry

Answer 32

@Preetha @perl can you plz help
