Graphing Rational Functions

Question 1

Consider the function f(x) = c x , where c is a nonzero real number.

Revolt · Accepted Answer

Consider the function f(x) = c x , where c is a nonzero real number.: is x = 0; Consider the function f(x) = c x , where c is a nonzero real number.: is y = 0; Consider the function f(x) = c x , where c is a nonzero real number.: is all nonzero real numbers; Consider the function f(x) = c x , where c is a nonzero real number.: is all nonzero real numbers

Question 3

Consider the following function:How does the graph of this function compare with the graph of the parent function, ?

Revolt · Accepted Answer

B: It is shifted left 5 units and up 2 units from the parent function.

Question 4

Revolt · Accepted Answer

D:

Question 5

Sound intensity, I, from a spherical source is a function of the distance, r, from the source of the sound. It is represented by the functionwhere P is the power of the sound. Explain the behavior of the graph of I and what it means in context.

Revolt · Accepted Answer

The function I = P / (4πr^2) has a vertical asymptote at r = 0, meaning the intensity is undefined at the sound source. As the distance r increases, the intensity I decreases toward zero, which is represented by a horizontal asymptote at I = 0. In context, this means that as you move further away from a sound source, the sound intensity drops rapidly and eventually becomes nearly silent.
