Basically, that means that the function is equal to zero when input=-2,2,and 3 the easiest one would be one wher you have xy where either one will be zero when you input -2,2,and 3 an easy example is f(x)=(-4)(x-3) if you subsituted -2 for x then you wuld do x^2=-2^2=4 then 4-4=0 so one factor is 0 then the whole thing is zero
if you subsituted 2 for x, then same thing
if you subsituted 3 for x then second thing x-3=0 so then it woul dequal zero
To find the perimeter of irregular shapes in general, you just add the length of the sides. To find the area of irregular shapes, first, draw a line to separate the two shapes, then find the area of those two shapes and add them up.
