The vertex of a parabola is (3,2). A second point on the parabola is (1,7). Which point is also on the parabola?
Answer choices include: (-1,7), (3,7), (5,7), and (3,-2)
Answer choices include: (-1,7), (3,7), (5,7), and (3,-2)
1 Answer
Explanation:
Method 1:
If you look at the graph, the only point that intersects the parabola is
graph{5/4((x-3)^2)+2 [-4.5, 15.5, 0.16, 10.16]}
Method 2: Use the Vertex Form of parabolas to find the equation of the parabola:
-> Use the provided values to plug into the equation.
-> Solve for
-> Solve for
->Plug a into vertex form of parbola.
-> Now, plug answer choices into the equation to see which one works with the equation.
-> Plug in
-> Since
