Step-by-step explanation:
The vertex form of a parabola:
(h, k) - vertex
We have the vertex at (3, 2) → h = 3 and k = 2.
Substitute:
The point (4, 6) is on athe parabola. Put the coordinates of this point to the equation:
<em>subtract 2 from both sides</em>
Finally:
<em>vertex form</em>
<em>use (a - b)² = a² - 2ab + b²</em>
<em>use the distributive property</em>
<em>standard form</em>
Answer:
5. <em>the given ordered pair is not a solution 6. the given ordered pair is a solution 7. the given ordered pair is a solution</em>
Step-by-step explanation:
5. 8 = -4(-2) => 8 = 8 (true)
8 = 1/2(-2) + 7 => 8 ≠ 6 (false)
<em>the given ordered pair is not a solution </em>
6. 3 + 5(1) = 8 => 8 = 8 (true)
4(3) - 5(1) = 7 => 7 = 7 (true)
<em>the given ordered pair is a solution</em>
7. -5 = 4 - 9 => -5 = -5 (true)
4 + (-5) = -1 => -1 = -1 (true)
<em>the given ordered pair is a solution</em>
