Question

What point is symmetric to (2,7) on this quadratic graph?

OPTIONS

• (-5,0)
• (-2,4)
• (2,-1)
• (-6,7)

Answer 1

Answer: (-6,7)

Explanation:

Tow points, (x1, y1) and (x2, y2) are simetric in a quadratic graph when:

f(x1) = y1 = f(x2) = y2

so y1 = y2

Then if we have the point (2,7) we want to find other point that has the same value for y, this is (-6, 7)

So the correct option is (-6,7)
