Transcribed Image Text:**Task Description:**
Plot the curve of the function \( z(t) = 3t^3 - 9t^2 + 8t \) in MATLAB, given \( t = -10:0.01:10 \).
**Explanation:**
1. **Function Definition:**
- The function is \( z(t) = 3t^3 - 9t^2 + 8t \), which is a cubic polynomial in terms of \( t \).
2. **Range of \( t \):**
- The variable \( t \) ranges from -10 to 10, with increments of 0.01.
3. **MATLAB Implementation:**
- You can plot this function in MATLAB using the following code:
```matlab
t = -10:0.01:10;
z = 3*t.^3 - 9*t.^2 + 8*t;
plot(t, z);
title('Plot of z(t) = 3t^3 - 9t^2 + 8t');
xlabel('t');
ylabel('z(t)');
grid on;
```
- The code defines the range of \( t \), calculates the corresponding \( z(t) \) values, and plots the curve with appropriate labels and grid.
