Answersadfs:
Domain of the exponential function is (-∞, ∞)
the range is (0, ∞)
Stasdfep-by-step explanation:
Domain is the set of x values for which the function is defined. there is no restriction for x in exponential function.
Domain of the exponential function is (-∞, ∞)
Range is the set of y values for which the function is defined
For range, of we plug in positive or negative number for x the value of y is always positive because we have exponent x
Hence the range is (0, ∞)

Answer:
C
Step-by-step explanation:
Note that <em>x</em> is opposite to the given angle and we are also given the hypotenuse.
Since we have an angle and the side opposite to it and the hypotenuse, we can use the sine ratio. Recall that:
The opposite side is <em>x</em>, the hypotenuse is 15, and the angle is 53. Substitute:
Solve for <em>x: </em>
