Which is the range of the function f(x) =(9)x?

f(x) =(9)x = 9x

It's linear function. Domain and range are all real numbers

Answer

Range is all real numbers

(0,∞)

Step-by-step explanation:

Given:

It is an exponential function whose base is 9.

If base is greater than 1 then function is growth exponential.

Domain: All real value of x.

Range: It is output value of function we get by putting x.

For x approaches to infinity , y → ∞

For x approaches to negative infinity, y → 0

Range: All positive real number.

Range: (0,∞)

Hence, The range of the given function is  (0,∞)

answer:

sometimes

*i think

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
