Question

Which of these statements is true for f(x)= (in."?A. The range of f(x) is y> 10B. The domain of f(x) is x>0.O c. The y-intercept is (0,1).O D. It is always increasing.

Answer 1

Given function is

`f(x)=((9)/(10))^x`

The range of the function is greater than 9/10 only for positive x.

We know that the exponential function is increasing.

Hence the function is increasing.

So the answer is D.
