When X is equal to four, The practical approach to figure out something like this is to try out various points and see if you can identify a pattern. take the negative of that to get to negative one. Here is the general rule for reflection across the y-axis: The inputs of the equation are being multiplied by {eq}-1 {/eq} since the x-coordinates represent the inputs of the equation. {/eq}-coordinate. g (1) = g (1) = -2 -2 -0.57 -7 Consider the three functions: f (x) = (4)x g (x) = (4)-x h (x) = - (4)x flip it over the y-axis? The reflection of such a parabola over the x-axis is simply written as y = -(x^2). Pickup. comparing between g(x) and y = -x^2, the y value is -1 as opposed to -4, and -1 is 1/4 of -4 so that's the scale.
