Find the value of x (either odd or even)..
5x^7 + 3x^4 = 241
your equation does not have an integer solution.
note $f(1)=-233$ and $f(2)=447$ ... since the function is continuous, there exists a value of $x$ in the interval $(1,2)$ where $f(x) = 0$
attached is a graph showing that single real zero
then the left-hand side is even because is it the sum of two odd numbers, and B) if x
is an even integer, then the left-hand side is even because is it the sum of two even
No specific values of x need to be substituted to do the problem. The corresponding
graph of f(x) = 5x^7 + 3x^4 need not be checked.
