Answer:
12 + 8k² + k³ - 9k⁴
Step-by-step explanation:
(8 + k³ - 6k⁴) + (4 - 3k⁴ + 8k²)
8 + k³ - 6k⁴ + 4 - 3k⁴ + 8k²
(8 + 4) + (8k²) + (k³) + (-6k⁴ -3k⁴)
(12) + (8k²) + (k³) + (-9k⁴)
12 + 8k² + k³ - 9k⁴
Answer:
<em>Observe the attached image</em>
Step-by-step explanation:
A function f(x) is even if
![f(-x) = f(x)](https://tex.z-dn.net/?f=f%28-x%29%20%3D%20f%28x%29)
This means that an input value x and -x have the same output value y
Therefore, check the graph and if it has equal values of y for the values of x and -x, then it is an even function.
Then the graph of
will have symmetry with respect to the vertical axis
Observe in the attached image the graph of ![f (x) = 2cos (x)](https://tex.z-dn.net/?f=f%20%28x%29%20%3D%202cos%20%28x%29)
It always has the same values of y for x and -x. Then
It's an even function.
