Answer 1

Answer:

The correct option is 4.

Step-by-step explanation:

The given function is

$f(x)=5(2)^x$

Put x=0,

$f(0)=5(2)^0=5\times 1=5$

Put x=1,

$f(1)=5(2)^1=5\times 2=10$

Put x=2,

$f(2)=5(2)^2=5\times 4=20$

Put x=3,

$f(3)=5(2)^3=5\times 8=40$

Only table 4 represents the correct value of the given function, therefore the correct option is 4.
