Question

Given y1, y2, and y3 as a function of x. In the same graph plot the three functions for x ?[-3,3] . Follow the form given below.

function y1 Line style: solid, color: blue function

y2 Line style: dashed, color: black function

y3 Line style: dotted, color: red

Label the x and y axis; x axis as (x), and the y axis as (y1,y2,y3), title the graph as (problem5), add a legend on the plot.

y1=x^4-e^(-x)

y2=x^2-x^3+25

y3=30-12x,

%Generate x array with increment 0.1
x = -3:0.1:3;

%Given expression and substitute x in that
y1 = x.^4 - exp(-x);
y2 = x.^2 - x.^3 + 25;
y3 = 30 - 12 * x;

%plot y1 y2 and y3 with given specification
plot(x,y1,'b-');
hold on
plot(x,y2,'k--');
plot(x,y3,'r:');
