By using the property of exponential function, the results obtained are
Base of the function is 5.
Initial value of the function is close to zero.
What are exponent?
Exponent tells us how many times a number is multiplied by itself.
For example : In
Here, 2 is multiplied by itself 4 times.
If (m times), a is the base and m is the index.
Here,
is an exponential function.
The base of the function is 5.
As , the function tends to 0
So the initial value of the function is close to zero.

Answer:
Choice D is correct
Step-by-step explanation:
The first step is to write the polar equation of the conic section in standard form by dividing both the numerator and the denominator by 2;
The eccentricity of this conic section is thus 1, the coefficient of cos θ. Thus, this conic section is a parabola since its eccentricity is 1.
The value of the directrix is determined as;
d = k/e = 3/1 = 3
The denominator of the polar equation of this conic section contains (-cos θ) which implies that this parabola opens towards the right and thus the equation of its directrix is;
x = -3
Thus, the polar equation represents a parabola that opens towards the right with a directrix located at x = -3. Choice D fits this criteria
