How do you reflect an image over the X-Axis?
change the y value to -y, and bring the negative over the equal sign. example. y=2x^2 reflected on the x-axis looks like y=(2x^2)/-1 which is equal to y=-(2x^2)
How do you reflect co ordinates on an x and y axis?
First you go over how many spaces then you go up how many spaces
How does the coordinate change when you reflect it over the origin?
The plus values become negative and the negative values become positive although their numerical values remain the same
What are the rules for points reflected over the x-axis?
The x value remains the same, but the y value changes sign
What relationship could be represented by a graph with a negative slope?
something which decreases over time e.g. speed of a car when the brakes are applied. Time on the x-axis and speed on the y-axis of the graph
How do you reflect over the y axis when your x axis is already negative?
The bit with the negative x-axis goes to the positive x-axis.
How do you reflect figures over x axis?
no
How do you reflect over the x axis when a point is over the x axis already?
To reflect a point in the x axis, multiply it's y coordinate by -1. Example: (x, y) over the x axis is now (x, -y), If you come across the y already being a negative, then make it a positive, (x, -y) = (x, y). The x stays the same, and vice versa over the y axis. Hope I helped. I am also having trouble with this, though, What if there is a zero? (5,0), it can't be (5, -0) can it?
How do you reflect a traingle over the x axis?
by looking and controling it
Which sequence of transformations will result in an image that maps onto itself?
reflect across the x-axis and then reflect again over the x-axis
How do you reflect over x axis?
You change the value of y to -y. ex: (4,5) reflected over the x-axis is (4,-5)
How do you reflect an image over the X-Axis?
change the y value to -y, and bring the negative over the equal sign. example. y=2x^2 reflected on the x-axis looks like y=(2x^2)/-1 which is equal to y=-(2x^2)
How do you reflect over x axis when y is negative?
When reflecting a point over the x-axis, you are essentially changing the sign of the y-coordinate while keeping the x-coordinate the same. So, if the original point has coordinates (x, -y), reflecting it over the x-axis would result in the new coordinates being (x, y). This transformation is a fundamental concept in geometry and can be applied to various shapes and figures to create mirror images across the x-axis.
Multiplying by a negative number flips the graph of a function over the -axis?
x
How do you reflect over the y-axis?
count the spaces on your graph until you reach the y axis then start over and count again till you count the same number that you it took you to reach the y axis... sounds kinda confusing.... but good luck !
How do you rotate a figure 90 degrees counter clockwise then reflect over y axis?
I dont really know if this is right but i think to do this problem you have to take a point then rotate the paper counter clockwise around the origin then you have a new point which is called a prime. Then reflect it over the y axis on the graph.
What is the equation for the axis of symmetry of a parabola?
x=-b/2a [negative B over 2A]
