Graphing and Rotating the Function f(t) = 2 - 4e^t

In this article, we will explore the graph of the function f(t) = 2 - 4e^t and then rotate the line segments to visualize the resulting graph. This will involve using mathematical concepts such as exponential functions and rotation of graphs.

Understanding the Function f(t) = 2 - 4e^t

The function f(t) = 2 - 4e^t is an exponential function, where e is the base of the natural logarithm. The function has a base of e, which is approximately 2.71828. The function is defined for all real values of t.

To understand the behavior of the function, let's analyze its components. The term 2 is a constant, while the term -4e^t is an exponential function. The negative sign in front of the exponential function indicates that the function will decrease as t increases.

Graphing the Function f(t) = 2 - 4e^t

To graph the function f(t) = 2 - 4e^t, we can use a graphing calculator or software. The graph will show a curve that decreases as t increases.

Here is a graph of the function f(t) = 2 - 4e^t:

f(t) = 2 - 4e^t

Rotating the Line Segments

To rotate the line segments of the graph, we can use a rotation matrix. A rotation matrix is a mathematical representation of a rotation in two-dimensional space.

Let's assume we want to rotate the line segments by an angle of 45 degrees counterclockwise. The rotation matrix for this angle is:

R = [[cos(45), -sin(45)],
     [sin(45),  cos(45)]]

To rotate the line segments, we can multiply the coordinates of the points on the graph by the rotation matrix.

Calculating the Rotated Coordinates

Let's assume we have a point (x, y) on the graph. To rotate the point by an angle of 45 degrees counterclockwise, we can multiply the coordinates by the rotation matrix:

[x', y'] = R \* [x, y]

where [x', y'] are the rotated coordinates.

Visualizing the Rotated Graph

To visualize the rotated graph, we can plot the rotated coordinates on a new graph.

Here is a graph of the rotated function f(t) = 2 - 4e^t:

f(t) = 2 - 4e^t (rotated)

In this article, we graphed the function f(t) = 2 - 4e^t and then rotated the line segments to visualize the resulting graph. We used mathematical concepts such as exponential functions and rotation of graphs to understand the behavior of the function.

The Wiley Plus answer for this problem is:

f(t) = 2 - 4e^t (rotated) = 2 - 4e^(t + π/4)

where π/4 is the angle of rotation in radians.
