Question

Graph y=3(x+2)^2-4
Label all parts on the graph and 5 points. Please help!!

Answer 1

Creating a Plot
The plot function has different forms, depending on the input arguments.

If y is a vector, plot(y) produces a piecewise linear graph of the elements of y versus the index of the elements of y.

If you specify two vectors as arguments, plot(x,y) produces a graph of y versus x.

For example, these statements use the colon operator to create a vector of x values ranging from 0 to 2π, compute the sine of these values, and plot the result:

x = 0:pi/100:2*pi;
y = sin(x);
plot(x,y)
Add axis labels and a title.

xlabel('x = 0:2\pi')
ylabel('Sine of x')
title('Plot of the Sine Function','FontSize',12)
The characters \pi create the symbol π and the FontSize property increases the size the text used for the title:
