PLEASE USE MATLAB COMMANDS THANK YOU
MATLAB CODE
%defining the function f(x) and g(x)
%. dot command allows for element wise multiplication this is
what allows us to use f1=f(x) and g1=g(x)
f=@(x) 3.*x.*sin(3.*x);
g=@(x) 12-2.*(x.^2);
%command to create x vector from -10 to 10 with 0.01
spacing
x=-10:0.01:10;
%producing the vector of f(x) and g(x) and storing in f1 and
g1
f1=f(x);
g1=g(x);
%Plotting x Vs f(x) and xVs g(x)
plot(x,f1);
%hold on is used to plot 2 many plots in one figure
hold on
plot(x,g1);
xlabel("x")
ylabel("f(x),g(x)")
legend("f(x)","g(x)")
OUTPUT
The intersection points can be seen on the graph
x1,y1=(-2.21,2.23) x2,y2=(2.21,2.23)

(c) Based on the graph, solve f(x)>g(x). (a) Choose the graph below that shows the intersection of f(x) = 5*-8 and g(x)=2x-5. The window display is [-10, 10, 1] by [-1, 14, 1). ОА. B. OC. a Q...
This is matlab questions,please use Julia and give me Julia commands process to slove the questions. (3) Find an interval [a,b] on which f(x) = x cos(x) and gle) = 7 / 7 satisfies g(x)=f(). Your interval must be in [0,2]. have endpoints accurate to the nearest thousandth, and be as large as possible. Construct a graph showing both fanda on [o, 2] and on which your interval is. visible. (2) Let g(x) = x'+1+56 log 14-3x). The function has...
For all questions, write commands in Matlab (or Octave) that you would use to solve the exercises, not the result. For all exercises, you must write the commands that you would use to solve them, not the result 1. Compute sin(/5), e2v17 +4.(-33) 2. Write an anonymous function with the formula f) sin 2 3. 3. Write the function above so that it can be applied to vectors of arguments 4. Graph the function from-5 to 5 How would you...
Use Newton's Method to approximate the x-value of the point of intersection of the two graphs of f(x) = 3x + 1 and g(x) = Vx+5 to 5 decimal places. Use your calculator to find the x-value of the intersection to 5 decimal places and calculate your error until your approximation matching the calculator's.
