Range for the given Exponential function 
is f(x) > 0.
the correction option is a). f(x) > 0
The function given in, the question is exponential function is given by
Which is an exponential function. The domain of the give function is (-∞, ∞).
<h3 /><h3>what is exponential function?</h3>
The function which is in format f(x) = 
where, a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
the Question seems to be incomplete. And options could be
a) f(x) > 0 c) f(x) ≤ 0
b) f(x) < 0 d) f(x) ≥ 0
Simplification of the given equation
clearly, the range of the exponential function is f(x) > 0.

22. Suppose that the teacher started recording on a digital camera with an hour available.
She gives 15 minutes introduction. Thus 60 minutes – 15 minutes is 45 minutes.
She still have 45 minutes remaining, now the question is how many minutes will remain if she uses 1 minutes per students.
Since the number of students is not given. It depends on how many students will be there. For example 25 students thus that’s equals to 25 minutes also. So she has a 20 minutes remaining.,
We know that
<span>the rotation of a solid does not modify the values of the internal angles of the solid
</span>therefore
interior angle after 90° rotation=interior angle before 90° rotation
interior angle after 90° rotation=108°
the answer is the option D 108 °
