having difficulties with integration
1. determine the area bounded by the curve y=x^2-3x+7, the x axis and the ordinates at x=1 and x=3
$\displaystyle f(x)=x^2-3x+7=ax^2+bx+c$
$\displaystyle b^2-4ac<0$ means that the graph does not cross the x-axis.
$\displaystyle f(0)=7\Rightarrow$ graph lies above the x-axis and the integration will give the area
between the curve and the x-axis.
Hence, integrate the three terms of the function and evaluate the result
from x=1 to x=3.
