Question

1,2,and 3 please I really need help

Answer 1

1) yes

2) Option B

3) 9200

Explanation:

1) yes

The exponential function is: y=-(x)^3

Putting the values of x in the given function we get the values of y.

x =1 , y= -(1)^3, y=-1

x= 2, y= -(2)^3, y = -8

x= 3, y= -(3)^3,y = -27

x= 4, y= -(4)^3,y = -64

2) f(x) = 160.2^x

if value of x = 2

then f(2) = 160.2^(2)

f(2) = 160.4

f(2) = 640

So, Option B is correct.

3) f(x) = 2300.2^x

if value of x = 2 decades then

f(2) = 2300.2^2

f(2) = 2300.4

f(2) = 9200

Since all options are not visible, so correct answer is 9200
