I have a very very simple quadratic function:
Now building a new tunnel that has a shape of parabolic curve. The tunnel is 10 m wide and at 4 m from either side, the height of the
tunnel is 6 m. Find the quadratic equation in standard form that
models the ceiling of the new tunnel.
The question is very simple, but I just can't understand what does at 4 m from either side mean in this question while mentioning the width in 10m?
I am not a native English speaker so it is hard for me understand what the information this question is asking.
Any comments and answers will be appreicated!
Edit: I see comments where people say that this question is badly word, I agree. Actually, this is a question I did on test and I just get the result today, none of the people in my class get the answer.
It not me made the question.
