Question

Somebody help with correct answer please and explain!??

Answer 1

I Belive the answer is b

Answer 2

Ok let's look at each answer individually:

A - it is always increasing
Let's substitute x = 1 into the equation: f(1) = 1/10
Now let's substitute x = 2: f(2) = 1/100
As we can see, the y values are getting smaller as x increases, therefor A is incorrect

B - The range of f(x) is y > 1/10
This graph has a horizontal asymptote of y = 0 and so the y-values will approach but never reach 0 as x increases, therefor B is incorrect

C - The graph contains (1, 10)
Now if we substitute x = 1 into the equation we get: f(1) = 1/10. Therefor C is correct!
