The equation y=0.452x^2+29.032x+170.976 with x equal to the number of years from 1988 to 1996, models a company's spending (in millions of dollars).

a. Graph this function for x=0 to x=8
b. If x=0 in 1988, find the spending by this model in 1994.

PLEASE HELP ME PLEASE

anonymous · Answer

will it a parabola,we know that, when x=0, y=170.976

anonymous · Answer

if x=0 is 1988, then 1994=1994-1988=6,

so plug in x=6 into your equation

whered u get 6 from

anonymous · Answer

it is a parabola that opens up and looks like this http://www.wolframalpha.com/input/?i=y%3D0.452x^2%2B29.032x%2B170.976
