If X A Y B Is The Solution Of Pair Of Equations X Y 2 And X Y 4 Find The Values Of A And B Brainly In
X = y 2 and y = x − 2 so y − 2 = y2 y 2 − y − 2 = 0 (y − 2)(y 1) = 0 We conclude that y = 2 or y = −1 We can plug these values of y back in to either equation to find the associated x values y = x − 2 2 = x − 2 4 = x If we perform a similar equation with y = −1 we'll find that the two points of Example 2 y = x 2 − 2 The only difference with the first graph that I drew (y = x 2) and this one (y = x 2 − 2) is the "minus 2" The "minus 2" means that all the yvalues for the graph need to be moved down by 2 units So we just take our first curve and move it down 2 units Our new curve's vertex is at −2 on the yaxis
