What is #5 I don’t know the answer.
denpristay [2]

If the axis of symmetry is x=-1, the vertex will have x-coordinate -1.

The point (0, 5) cannot be the vertex. The friend is not correct.

_____

If the point (1, 5) is on the graph so is the image of that point when it is reflected across the axis of symmetry. That image point is (-3, 5). A parabola that goes through points (1, 5) and (-3, 5) will not go through point (0, 5).

Hello there!
Goryan [66]

(x^2+3)^2 + 7x^2+21=-10

We want to convert this equation in terms of m, where m = x^2+3

While solving this problem, I instantly noticed the x^2+3 in the first term of the equation. Replace that with m.

m^2 + 7x^2+21=-10

Simplifying the rest is not as obvious. Using the distributive property, we can change [7x^2+21] to [7(x^2+3)]

Do you see the "m" in here? Look again if you don't.

Now we can simplify the equation to m^2 + 7m=-10 and this cannot be simplified further.

I'm always happy to help someone who appreciates the help! :D
