Question

Can someone please help me!! I did most of it but I do not know what to write for the last question d. Can someone help me ASAP please.
A video game designer decides to include a character in a new game that only moves along a parabolic path. The designer uses the function y=-x^2+50x+10 to model this character’s path, where y is the height of the character in pixels and x is the time in seconds that it takes the character to move across one parabolic path.

a. Is the vertex of the function a maximum or minimum point and how can you tell?

b. Find the x-coordinate of the vertex. Show all work leading to your answer and write the answer in simplest form.

c. Find the y-coordinate of the vertex. Show all work leading to your answer and write the answer in simplest form.

d. Write the vertex as an ordered pair (x, y). What does the vertex represent for this
situation? Write 1-2 sentences to explain your answer.

Answer 1

Ok, for the last question you have to do something called factoring which you can do by using the method A which equals 1 B which equals 50 C which equals 10 then you get 50 and 10 you have to find two numbers that multiply to equal ten but add up to equal 50. hope this helps :)
