Question

What is the graph of the function?

y = 2 · 2^x

Answer 1

first is out, graph is going down when it should be going up

Answer 2

fourth is out for the same reason

Answer 3

second looks good
you have \((1,4)\) on the graph and \(2\times 2^1=4\)

Answer 4

also \((2,8)\) is on the graph, and \(2\times 2^2=8\) so i would go with the second option

Answer 5

y = –2 · 5x

Answer 6

this is for the second graph.

Answer 7

\[y=2*2^x=2^{x+1}\]

Answer 8

Do any of ya'll know this?

Answer 9

not 1 or 3 or 4

Answer 10

so it's the 2nd one again?

Answer 11
