Quadratic Graph Example Y Ax Expii
Learn the rule To get the ycoordinate of the vertex, after finding the xcoordinate of the vertex, substitute the value of the xcoordinate of the vertex x in the original equation So the y coordinate of the vertex is or That makes the vertes ( , ), or (05,85) and we see that looks right according to the graphAll equations of the form a x 2 b x c = 0 can be solved using the quadratic formula 2 a − b ± b 2 − 4 a c The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction x^ {2}2xy48=0 x 2 2 x − y − 4 8 = 0 This equation is in standard form ax^ {2}bxc=0 Substitute 1 for a, 2 for b, and 48y for c in the quadratic formula, \frac {b±\sqrt
