Equation for reflecting over x axis
-f (x) = Reflection across x-axis f (-x) = Reflection across y-axis These are essential to know. Since -f (x) is a reflection across axis, we do as such: -f (x) = -1 (-4 (x+7)²-7) -f (x) = 4 (x+7)²+7 <-- you're new equation ( 6 votes) Fred Haynes 3 years ago Why does f (x) = the square root of x make the type of graph it does? • ( 3 votes) kubleeka WebTopics Reflections and Rotations. Reflections and Rotations We can also reflect the graph of a function over the x-axis (y = 0), the y-axis(x = 0), or the line y = x. Making the output negative reflects the graph over the x …

Weby = 7x means for every x, y is 7 times as large. This produces a very steep line. The same thing applies here. "Scaled vertically" is a fancy way of saying the line looks steeper (i.e. stretched along the y-axis). y = 7 x means for every x, y is 7 times as large. On the other hand, y = x + 7 means you add seven to each x to get y. ( 1 vote) WebStep 1 : Apply the rule to find the vertices of the image. Since there is a reflection across the x-axis, we have to multiply each y-coordinate by -1. That is, (x, y) ----> (x, -y). Step 2 : A (1, -3) ----> A' (1, 3) B (4, -1) ----> B' (4, 1) C (6, -5) ----> C' (6, 5) Step 3 : Graph the triangle ABC and its image. Example 2 :
