1 divided by X+5+2

Question

graph and find domain and range

Answer 1

1/(x + 5 + 2) = 1/(x + 7)

when working with fractions, you can't divide by 0 so set x + 7 = 0

then x cannot equal -7

so Domain is all reals except -7

you have a vertical asymptote at x = -7 and a horizontal at y = 0

if you don't have a graphing calculator then use an x-y table to plot other points
