I need help please. Do these functions increase or decrease,  and give the end behavior. (I)f(x)=4x-1/4

f(x)  =  4x- 1/4


In the form  mx - b......   m  = 4  = the slope....which is positive......then this function "Rises' [ increases ] from left to right....the end behavior on the left is toward negative infinity....and on the right it is positive infinity



f(x)  = (-1/2)x  + 3


The slope is negative  and this function "Falls" [ decreases] from left to right......the end behavior on the left is toward positive infinity....and on the right it is negative infinity


Here are the graphs of each  : https://www.desmos.com/calculator/g36i8bra7n
