55) Which of the following has a graph that is symmetric to the x-axis?
y = x
y2 = x
y = x3 - x
y = x2 + 3
What is the answer to the question and why? Can you please explain to me how to do these types of problems??
EASY 10 POINTS!!

No, it's not y = x. That's only symmetric about the origin.
it would be the second one, y^2 = x. If you could graph this, you would get the graph of y = x^2 but turned sideways and opening to the right. It's symmetric to the x axis because you could negate your y coordinates and get the same graph.

y=x
Because to be symmetric both points have to be the same so x=y or 1=1, 2=2 e.t.c

the graph will be symmetric to X-axis if
X= f(y)=f(-y)
in the above case it is only true for y^2=x
similarly for Y-axis the condition will be
y=f(x)=f(-x)

Well, you need to add up the numbers of hens, pigs, sheep, horses, and cows. Then you take the number of the animal you're referring to and divide it by the total number you just found. Say, for part a, you take the total number of pigs (12) and divide it by the total number of animals (10 hens + 12 pigs + 10 sheep + 8 horses + 6 cows) to get your fraction. You do the same for c. For b, you add the numbers of sheep (10) and horses (8) and take that number, 18, out of the total number of animals. And then for d, you put the fractions in order from the smallest fraction to the biggest one. Because you're using the numbers of pigs (12), hens/sheep (18), and cows (6), the cow fraction will end up being smallest, followed by pigs and then hens/sheep. But make sure you put the fractions and not these original numbers! Good luck :)

Make a data table. Note that for y² = x, y is not a function of x.

I remember that y=x is a horizontal line that passes through where x & y meet, like this ( / )

y^2=x
For each value of of +/- y there is one value of x.
