MATLAB Problem

HW7P2 (20 points) (5 pts) Write a user-defined MATLAB function called HW7P2_fn for the following math function 3 o-0.47x The input to the function is x and the output is y. Write the function such that x can be an array (use element-by-element operations) (15 pts) Use the function in (a) the command window to calculate y(-2) and y(5) (b) a script file HW7P2.m to determine y(x) for 0.001 Sx S 10 with 1000 points. Hint: Use the linspace function to create the x vector (c) In the same script file HW7P2.m, plot the function v(x) 4 times in 2 by 2 subplots using the following 1. 2. 3. 4. Linear scale for both the x and y axes Linear scale for the x axis and logarithmic scale for the y axis Linear scale for the y axis and logarithmic scale for the x axis Logarithmic scale for both the x and y axes Use the axis () function to adjust the limits of the x axis from the minimum value of x to the maximum value of x and the same for the y axis. You can use the functions min () andmax () in MATLAB after reading their help sections
