Use technology to determine PLEASE HELP I WILL MARK U BRAINLIEST. the vertex of each quadratic
Arte-miy333 [17]

9514 1404 393

Answer:

  • vertex: (7.5, 2.25)
  • f(x) = -(x -7.5)² +2.25

Step-by-step explanation:

My favorite "technology" for problems like this is the Desmos graphing calculator app or web service. It easily displays the vertex (and/or zeros) of the function.

Of course, vertex form is ...

  f(x) = a(x -h)² +k . . . . . . . . vertex (h, k), leading coefficient 'a'

The solution is found by reading the graph and putting the numbers in the formula. The leading coefficient is copied from the standard form equation.

  • vertex: (7.5, 2.25)
  • f(x) = -(x -7.5)² +2.25
