Answer:
The second function represents an even function; 
Step-by-step explanation:
A function f(x) is said to be even if f(x) = f(-x). All we need to do is replace x with -x in each equation, simplify it and assess whether the equation remains unchanged. If the equation is identical to the original one then it is said to be even. Another good example of an even function is the cosine function. Moreover, even functions have y-axis symmetry

Step-by-step explanation:
Answer:
$6062
Step-by-step explanation:
The formula we are given is
![c=120\sqrt[3]{n^2}+1300](https://tex.z-dn.net/?f=c%3D120%5Csqrt%5B3%5D%7Bn%5E2%7D%2B1300)
We will replace n with 250:
![c=120\sqrt[3]{250^2}+1300\\ \\=120\sqrt[3]{62500} +1300\\\\=120(39.685)+1300\\\\=4762.20+1300\\\\=6062.20 \approx 6062](https://tex.z-dn.net/?f=c%3D120%5Csqrt%5B3%5D%7B250%5E2%7D%2B1300%5C%5C%20%5C%5C%3D120%5Csqrt%5B3%5D%7B62500%7D%20%2B1300%5C%5C%5C%5C%3D120%2839.685%29%2B1300%5C%5C%5C%5C%3D4762.20%2B1300%5C%5C%5C%5C%3D6062.20%20%5Capprox%206062)
