Question #e1123
1 Answer
graph{x^2 - 5 [-15.8, 15.82, -7.9, 7.9]}
Explanation:
1) The key to graphing functions is to look at what I call the "mother function". In this case, the mother function is simply
2) The graph of
3) Now we also have
If it was, let's say,
OR
You can graph it by plotting points which in my opinion takes unnecessary time, but here is how you do it:
1) write your equation
2) Plug in different values for
For example, plugging
#y = 0^2 - 5#
So your
Plugging
#y = (-3)^2 - 5#
which equals
3) but even with plotting points, the key is that you still need to know what your "mother functions" look like.
The graph of
