Question

For the given graph, find
(a) the domain
(b) the range
(c) the x-intercept(s)
(d) the y-intercept(s)
(e) the graph’s symmetry (x-axis, origin, y-axis, or none of these)

Answer 1

domain = valid x values (all x values that there's a point on the graph for)
range = y values that you can obtain (all y values that there's a point on the graph for)
x-intercepts = where the graph cuts the x-axis (where y=0)
y-intercepts = where the graph cuts the y-axis (where x=0)
symmetry = can you fold the picture along a line & it's like the line is a mirror?

Answer 2

Domain: Set of Reals
Range: Set of Reals
x-intercept (0,0)
y-intercept (0,0)
symmetry --> Graph appears to have symmetry about (0,0) a.k.a. the origin.

Answer 3

Thanks guys

Answer 4

Directrix - don't you think love31 is better off working it out alone, by being what the terms mean, rather than just hand the answer over on a platter?

Answer 5

He and I have been working together long enough for me to know that he will ask questions about the solution. Plus, he corrected one of my oversights just now. Love31 is new to this site. As he "ages" within the site, I will consider your suggestion. Thanks.

Answer 7

Directrix - ok, no problem - I'll defer to your exerience with working with love 31.
I wasn't tetsy, just keen for people to learn HOW, rather than have someone else do their homework FOR them.

Answer 8

Understood and no worries.
