Q:
sketch the graph of the equation.
x+=+2y%5E2-4
Label the x- and y-intercepts. (If an answer does not exist, enter DNE.)
----------------------------------------------------------
A:
To get the x-intercept/s, let y = 0 then solve for x:
x+=+2%280%29%5E2-4+=+-4
The x-intercept is (-4,0)
To get the y-intercept/s, let x = 0 then solve for y:
0+=+2y%5E2-4
y%5E2+=+2
y+=+sqrt%282%29 or y+=+-sqrt%282%29
(smaller y-value)
y-intercept
(x, y) = (0, -sqrt%282%29)
(larger y-value)
y-intercept
(x, y) = (0, sqrt%282%29)
Here's the graph:
