find the area between the graph of $\displaystyle y= 6x^2 - 42x + 60$ and the x-axis, between x=1 and x=4.
any ideas? thank you
How can an area between the curve and the x-axis be negative?
The answer has to be positive. Did you draw the graph?
It looks like you haven't taken the magnitude of $\displaystyle \int_2^4 6x^2 - 42x + 60 \, dx$ like I said to. But without seeing th details of your calculation it's impossible to know for sure what mistakes you have made.
