Hey guys, I'm having trouble with this problem, maybe you can help me out?
Let f (x) = 72 + x - x2 and g (x) = x2 - 9x.
Find the area between the graphs of f and g over [1, 6].
I tried that brother! Except the graphs cross at 4.3245, so, from what I think I've learned haha , I split it into two parts, integrating from 0 to 4.3245 and 4.3245 to 6. f(x)-g(x) for the first part because f is higher than g, then g(x)-f(x) for the second part, because g was higher than f. Where am I going wrong?
