Use the image to answer the question.
A coordinate plane shows a parabola that opens downward. The x-axis ranges from 0 to 15 in increments of 5. The y-axis ranges from 0 to 15 in increments of 5.
The graph shows the trajectory of a firework. Which equation in vertex form matches this graph?
Responses
y=12(x+5)2+10
y is equal to 1 half times open paren x plus 5 close paren squared plus 10 - incorrect
y=−12(x−5)2−10
y is equal to negative 1 half times open paren x minus 5 close paren squared minus 10 - no response given
y=12(x−5)2+10
y is equal to 1 half times open paren x minus 5 close paren squared plus 10 - no response given
y=−12(x−5)2+10
y is equal to negative 1 half times open paren x minus 5 close paren squared plus 10 - not selected, this is the correct answer
