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.

Answer:
A
Step-by-step explanation:
I did the math! and got 15
Hope this helps!
Al you have to do is add 4 to the equation
This gives you g(x)=4x^2+9 which is your answer
Corey will use 12 tablespoons
Since 4 tablespoons are in each 1/4 of a cup
