For the function, y=1%2F%28x-2%29+
a) give the y values for x=-1,0,1,2,3,4
If x=-1, then y=1%2F%28x-2%29+
y=1%2F%28-1-2%29+=-1%2F3

If x=0, then y=1%2F%28x-2%29+
y=1%2F%280-2%29+=-1%2F2

If x=1, then y=1%2F%28x-2%29+
y=1%2F%281-2%29+=1%2F%28-1%29=-1

If x=2, then y=1%2F%28x-2%29+
y=1%2F%282-2%29+=1%2F0= Undefined!!

If x=3, then y=1%2F%28x-2%29+
y=1%2F%283-2%29+=1%2F1=1

If x=4, then y=1%2F%28x-2%29+
y=1%2F%284-2%29+=1%2F2

b)using points, draw a curve (graph)
