What have you tried so far?
I'd work with the formula: integral of g(x) - f(x)
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?
