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.
<u>Solid figure</u><u> is also known as flat </u><u>two-dimensional</u><u> shape which only has length and width.</u>
- Geometrically figure , 2-dimensional shapes or objects are flat planar figures with two dimensions—length and width.
- Shapes that are two-dimensional, or 2-D, have only two faces and no thickness.
- Two-dimensional objects include a triangle, circle, rectangle, and square.
What geometric figure is also known as a flat?
- A closed two-dimensional, or flat, figure is called a plane shape.
- Different plane shapes have different attributes, such as the number of sides or corners (or vertices).
- A side is a straight line that makes part of the shape, and a corner, or vertex, is where two sides meet.
What geometric figure is also known as?
Geometric figures are often classified as space figure, plane figure, lines, line segments, rays, and points depending on the dimensions of the figure.

Answer:
14
Step-by-step explanation:
x * 2 = 8
y * 3 = 6
6 + 8 = 14
