The amount of radioactive uranium changes with time. The table below shows the amount of radioactive uranium f(t) left after tim

aniked [119]

Answer:

$f(t) = 100(0.25)^t$

Step-by-step explanation:

The general exponential function is,

$f(t)=ab^t$

The points given in the table are,

$(0,100),(0.5,50),(1,25)$

Putting $(0,100),(1,25)$ in the general equation, we get

$\Rightarrow 100=ab^0$

$\Rightarrow a=100$

And

$\Rightarrow 25=ab^{1}$

$\Rightarrow ab=25$

Putting the value of a,

$\Rightarrow 100b=25$

$\Rightarrow b=0.25$

Now the exponential function becomes,

$f(t) = 100(0.25)^t$
