Question

Determine the elements in the domain and range of G = { ( x, y) | y=(x-2)^2+x
and x is a positive integer less than 6 }.
The range of G is
a. {1,2,3,4,5}
b. {2,4,8,14}
c. {2,4,8,14,22}
d. {1,2,3,4,5,6}

Answer 1

This is a parabola, you'll need to find what value are in the range you described

Answer 2

So, for the first value of the range (Range is the y-values), you simply plug in the 6
y=(6-2)^2+6
y=4^2+6
y=16+6
y=22
