Use a graphing utility to graph the function and the damping factor of the function in the same viewing window.
f(x) = e−3x sin(x)

analyze the graph of the function using the method in example 6. (enter your answers as a comma-separated list. use n to represent an arbitrary integer if necessary.)
y = ±e−3x touches y = e−3x sin(x) at:

y = e−3x sin(x) has x-intercepts at:

The function touches the damping factor

at x= and x=

The x-intercept of f(x) is

at x=

Step-by-step explanation:

Given function is f(x)= and damping factor as y= and y=

To find when function touches the damping factor:

For f(x)= and y=

Equating the both the equation,

x=

For f(x)= and y=

Equating the both the equation,

x=

Therefore, The function touches the damping factor x= and x=

To find x-intercept of f(x):

For x-intercept, y=0

f(x)=

y=

Hence, is always greater than zero.

Therefore,

x=

Thus,

The x-intercept of f(x) is at x=

Do the math. she originally had 50 dollars on her gift card and she had 12 dollars left on her gift card after she finished her shopping spree. if you subtract 50 minus 12 you get thirty eight dollars as your answer. so therefore, ciara spent 38 dollars total o
