- phi

if you think of it as
y= 2x
and then add 1
y= 2x+1
that is the equation of a line.
find two points, plot them , and draw a line through the two points.

Alright. I think I understand. So, if I were to type this into desmos.com what would I do?

- ali2x2

type in f(x) + 1 then press add slider i think

ok let me try

@peachpi What r ur thoughts

- anonymous

my thoughts are to type in the equation @phi gave

- anonymous

kk. Thanks:) Can I ask another question?

Given the parent function f(x) = 2^x, which graph shows f(x) + 1?
Going back to the 1st question, the f(x)=2^x is a logarithmic ! So now how do I graph it??

- anonymous

- phi

y= 2^x is exponential
when x is 0 you have y= 2^0 = 1 (any base to the zero power is 1)
x=1, y= 2
x= 2, y= 4
x=3, y=8
plot those points, and put a smooth curve through them
if you want
y= 2^x + 1 , and 1 to each of the y values:
(1,3)
(2,5)
(3,9)
etc.
|dw:1438809101764:dw|
the curve looks roughly like

ok! so what would be some points it touched?

- anonymous

(-5,1) and (3,5) or (0,2) (-5,1)

- phi

some are posted up above.
but follow the formula
y=2^x + 1
means: multiply 2 by itself x times (or just use a calculator)
then add 1

- phi

how did you get (-5,1) ?

- anonymous

Whoops! I have no idea

- phi

do you have a calculator? what do you get for 2^-5 ?

- anonymous

wouuld (0,2) be a point?

- anonymous

0.0315

- phi

then add 1
(-5, 1.0315)
for x=0, y= 2^0 + 1 = 1+1= 2
so (0,2)
x=1, 2^1 + 1 = 2 + 1 = 3
so (1,3)
you should be able to find a few more.

- anonymous

Oh! Okay thanks so much:)

I need help w/ 1 more. I am going to post it in the open question section:)
