If it does not, you probably did something wrong. If [latex]|a|>1[/latex], the point associated with a particular [latex]x[/latex]-value shifts farther from the [latex]x[/latex]axis, so the graph appears to become narrower, and there is a vertical stretch. Well, actually, let This idea of reflection correlating with a mirror image is similar in math. The reason the graph shifts up instead of down when you subtract a number from y is because (if you think about it) subtracting from y is the same as adding that number to the opposite side of the equation which results in a. And then if A is less Refer to the vectors u1\mathbf{u}_{1}u1 to u8\mathbf{u}_{8}u8. Well, now as we But if [latex]|a|<1[/latex], the point associated with a particular [latex]x[/latex]-value shifts closer to the [latex]x[/latex]axis, so the graph appears to become wider, but in fact there is a vertical compression. The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the -value the same. -4 \\ And if you'll eventually do, and it helps me a lot with homework and anything involving math. 5/5 recommend, and it's free. So if A is equal to 1, it's going to look the same. The equation will simplify to y-k=0. Let A(x)=x2/2A ( x ) = x ^ { 2 } / 2A(x)=x2/2 . You may learn further on how to graph transformations of trigonometric functions and how to determine trigonometric functions from their graphs in other sections. But now for this So here, no matter what -1 u5=211,u6=031,u7=342,u8=113. The function represents the remaining time in minutes needed to fill the tank. -1 \\ And then if A is negative I'm doing a very rough drawing here to give you the In this case, the x axis would be called the axis of reflection. 1 \\ 1 Track Way is a great place to go for a run. O. So let's think about x When drawing reflections across the x x and y y axis, it is very easy to get confused by some of the notations. Write the equation of the following description. it as cleanly as I can.
