Full solution

Q. A parabola opening up or down has vertex (0,1)(0,1) and passes through (8,9)(8,9). Write its equation in vertex form.\newlineSimplify any fractions.
  1. Find 'a' Value: Now we need to find the value of ' extit{a}' using the point (8,9)(8,9) that lies on the parabola.
  2. Solve for ' extit{a}': Next, we solve for ' extit{a}' by isolating it on one side of the equation.
  3. Substitute aa Value: Finally, we substitute the value of aa back into the initial form of our parabola's equation to get the equation in vertex form.
