A sum of $29,000 was invested in three mutual funds. In one year the first grew 4%, the second by 5%, and the third by 7.5%, total earning were $1723. The amount invested in the third fund was $1000 less than combined amount invested in the other two funds. use linear system of equations to determine the amount invested in each fund. Use the simple interest formula to calculate each fund growth.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

135 is your answer
