For which values of x element of the real numbers lays the graph of the function f with function rule f(x) = 2x^4 + 2x^2 below the graph of the function g with function rule g(x) = 5x^3 + 5x? Thank you!
1 Answer
Explanation:
If the graph of the function
we must have
or
or
or
or
but
hence we should have
or
This will be
either when
or when
That is
This is apparent from the following graph of two functions (not drawn to scale i.e. compressed along
graph{(5x^3+5x-y)(2x^4+2x^2-y)=0 [-4, 5, -50, 200]}
