Question

10. The point (–5, 1.5) is on the graph of x^2-4y^2=16
. Use symmetry to find one more point on the graph.

Answer 1

The function is an even function. Meaning if you put in a -x or a +x you get the same result.

So (5, 1.5) is another point on the graph.

Answer 2

(5, 1.5)
(5, -1.5)
(-5, -1.5)
(-5, 1.5)

Answer 3

the curve is symmetric about x-axis and y-axis.
