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
Add the exponents if the bases are the same, multiply the bases if the exponents are the same, if nothing is the same just solve it.
