Question

Which equation has a graph that is a parabola with a vertex at (5, 3)?

Answer 1

Answer:

y = a(x² - 10x + 25) + 3

Step-by-step explanation:

From standard form of an equation, of a parabola, we have;

y = a(x - h)² + k

We are told that the parabola has a vertex at (5, 3). Which in essence is (h, x)

Thus;

y = a(x - 5)² + 3

y = a(x² - 10x + 25) + 3

Therefore, the equation that has a graph that is a parabola with a vertex at (5, 3) is;

y = a(x² - 10x + 25) + 3
