Question 1:
Plot a graph for following lists with red color and dashed style:
X = [1, 2,3,5,7,7.5,8,10];
Y = [2,6.5,7,7,5.5,4,6,8]
Question2:
Plot a function with following input using magenta color and * markers:
x starting from -2 till 4 with a step of 0.3;
Y = 3.5^(-0.5x) *cos(6*x);
Question 3:
Plot the function y =3x^3-26x +0 and its first and second derivates for limit -2<= x <=4, all in the same
plot with different colors and style.
