Answer 1

where are the choices?

Answer 2

Answer:

See the attachment below.                            

Step-by-step explanation:

Given : The function $f(x) = 100(0.7)^x$

To find : The graph of the given function

Solution :

Let y=f(x)

$y = 100(0.7)^x$

Put in x = 0 we get,

$y = 100(0.7)^x$

$y = 100(0.7)^0$

$y = 100(1)$

$y = 100$

So (x,y) = (0,100) is one point on this function curve

Put in x = 2 we get

$y = 100(0.7)^x$

$y = 100(0.7)^2$

$y = 100(0.49)$

$y = 49$

So (x,y) = (2,49) is another point on this curve

For the graph we can see the attached figure.
