Question

what is tge equation of the line of symmetry for the graph of y=-2(x-4)^2+3

Answer 1

Bill, you there?

Answer 2

OK

Answer 3

So if the inside of the parentheses is (x-4), for a quadratic equation, the graph "moves" over 4 units to the right.

Answer 4

If the inside of the parenthesis is just (x), then the line of symmetry is the y axis.

Answer 5

So by "moving" the graph over, you move the line of symmetry as well.

Answer 6

Since it is "moved" over 4 spaces, the line is x=4

Answer 7

That's it?

Answer 8

Yes

Answer 9

Yes

Answer 10

Remember

Answer 11

Thanks

Answer 12

The equation of a quadratic equation is a(x-h)^2+k

Answer 13

The line of symmetry is always x=h

Answer 14

And the vertex is (h,k)

Answer 15

No problem, and good luck on your homework assignments.
