Question $2.$b

# Create a function "area$\_$to$\_$the$\_$left", which takes a single variable

# $($x$1)$ and calculates the area to the left, returning a value between

# $0$ and $1.$ The basic setup of the function is defined below. Note that

# you will need to use a slightly different equation if x$1$ is less than or

# greater than $3.$

# Hint: for a triangle with height H and base B$,$ the height of the subtriangle

# with width Y$\%$ of B is Y$\%$ of H$.$

area$\_$to$\_$the$\_$left$<-$function$($x$1)\{$

if$($x$1<0)\{$

# Area to the left of $0($or less$)$ is $0.$

return$(0)$

$\}$ else if $($x$1<3)\{$

# Area to the left of $5($or more$)$ is $1.$
