Try this option:
the rule: if f(-x)=f(x), then the function f(x) is even, if f(-x)=-f(x) then the function is odd.
1. f(x)=-5x⁴-2;
if to substitute x→(-x), then f(-x)=-5*(-x)⁴-2; ⇔ f(-x)=-5x⁴-2, in other words f(x)=f(-x), it means that this function is even.
2. f(x)=x³+2x.
if to substitute x→(-x), then f(-x)=(-x)³+2*(-x); ⇔ f(-x)=-(x³+2x), in other words f(-x)=-f(x), it means that this function is odd.
The first one is undefined and the second one is 1/2
Answer:
See explanations
Step-by-step explanation:
We have only one equation which is:
The number of equation is 1.
This means that, there are infinitely many solutions to the given equation.
To find a solution, we choose a value for x, substitute it into the equation and then solve for y.
For instance, when x=0, we have:
Therefore (0,2) is one of the solutions.
