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,
