Symmetry

In chapter three, I learned about the nature of graphs. I learned that a circle has infinite amity. Some graphs whitethorn show a line of correspondence or summit in time symmetry. In order to audition if a line has symmetry at the x-axis, the y-axis, at y = x, or y = -x, I learned that you must pick a back breaker that leave behind solve the equality and establish the point for the x-axis, the y-axis, at y = x, and y = -x. For example, in x2 + y = 3, I chose the point (1,2) because 12 + 2 = 3. To test for the x-axis I used, iff f(a,b)=f(a,-b) and past (1,-2). If I wad these points, (1,-2) into the professional equation, thence the equation is false. Therefore it is not bilateral at the x-axis. To test for the y-axis I used iff f(a,b)=f(-a,b) then (-1,2). This point makes the original equation true; so it is symmetrical at the y-axis. At y = x I used, iff f(a,b)=f(b,a) then (2,1). This point make the original equation false, therefore there is no symmetry at y = x. To test y = -x, I used iff f(a,b)=f(-b,-a), then (-2,-1). This point makes the original equation true, therefore there is symmetry at y = -x. I excessively learned that if the highest form in a dish up is even, then the prevail is even. If the highest degree in the function is odd, then the function is odd. I learned about the families of graphs.

They are as follows: y = x y = x2 y = x3 y = Radical x y = [x] ! y = x y = 1/x y = Cubed root of x If the coefficient is greater than one, the values lettuce faster and the graph becomes steeper. If the coefficient is less(prenominal) than one, then the values give add-on slower, and the graph will be less steep. If the coefficient is less than zero, then it is a vertical flip.
