Answer:
We conclude that the range of the function is 'all positive real numbers'.
Thus, option (A) is true.
Step-by-step explanation:
Given the expression
Determining the domain:
The domain of a function is the set of input values for which the function is real and defined.
It is clear that the given function has no undefined points nor domain constraints.
Therefore, the domain is: -∞ < x < ∞
Thus,
Determining the range:
The range is the set of values of the dependent variable for which a function is defined.
We know that the range of an exponential function of the form
In other words, the range is all positive real numbers.
Thus,
Therefore, we conclude that the range of the function is 'all positive real numbers'.
Thus, option (A) is true.
Is between 0 and 1 the image is a reduction. If the scale factor is greater than 1, the image is an enlargement.

Answer:
Option C. will be correct.
Step-by-step explanation:
The equations of straight lines are given as
3y - 5x = 15 ........... (1)
And, 6y - 10x = 30 ......... (2)
If we divide the equation (2), by 2 then we will get 3y - 5x = 15 which is nothing but the equation (1).
Therefore, those two equations (1) and (2) represents the same straight line.
Now, from equation (1), we can write .
This is an equation of a straight line in slope-intercept form and here slope is positive.
Therefore, Option C. will be correct. (Answer)
