Question

suppose f(x)=x^3+1. find the graph of f(2x)

Answer 1

i don't understand it at all

Answer 2

we are given the function
\[f(x) =x^3+1 \]
that should be graphed first
and then we apply the f(2x) in this case x = [2x] into the original function and that modification should be graphed second.

Answer 3

I agree with @UsukiDoll

Answer 4

:) thank you @arindameducationusc

Answer 5

the graph will be a stretch of factor 2 of f(x) parallel to the y-axis.

Answer 6

which one has that stretch?

Answer 7

i think the third down

Answer 8

This should help for more....

Answer 9

well its not easy to see unless you have the graph of x^3 + 1 also

Answer 10

true

Answer 11

ff(2x) will bring the graph closer to the y-axis. It will still go through the point (0,1)

Answer 12

i think its B

Answer 13

- but you really need to draw them to make sure

Answer 14

graph f(x) = x^3+1
and then apply the f(2x)
your modified function should look like this
f(2x)=8x^3+1

Answer 15

yes

Answer 16

to see the graphs go the desmos calculator web site

Answer 17

very roughly the graphs are
