Answer:
Alternative A is the correct answer.
Step-by-step explanation:
For a function to have y-axis symmetry then it must be an even function such that; f(-x) = f(x). In alternative A, y = x^2 is an even function since; y(-x) = (-x)^2 = x^2 = y(x). The second function is also even since it has the absolute symbol. Finally, the cosine function is always an even function since cos(-x) = cos(x)

1/5 divided by four is 1/20
5x4=20
Hey there!
We can set this up a proportion to figure out the percent we need.
If you can see, the second numerator is four times the first. So, we multiply the bottom by four and we get 20.
Therefore, the probability if observing at least one mistake made by this professor is 20%.
