A high diver jumps off a springboard. The equation that represents the path of the diver is f(x)=-4.9x^2+8x+10, where x is the time in seconds and f(x) is the height above the water's surface in meters. Please draw and labet the graph. I need to know the Xmin= Xmax= Xscl= Ymin Ymax= Yscl= Thank you

OpenStudy (saifoo.khan):

you want vertex and?

OpenStudy (anonymous):

yes

OpenStudy (saifoo.khan):

$vertex = (\frac{40}{49}, \frac{450}{49})$

OpenStudy (anonymous):

is there a way to graph that?

OpenStudy (mimi_x3):

Don;t you find the derivative first ?

OpenStudy (anonymous):

I have no idea...I just moved to a new school..and the teacher gave me homework on something I wasnt even here for

OpenStudy (saifoo.khan):

why will be find the derivative?

OpenStudy (mimi_x3):

Um, to find the min and max ? it's a parabola

OpenStudy (saifoo.khan):

we can also find that by other ways. :p

OpenStudy (mimi_x3):

But finding the derivative is the easiest way =/
