You can put this solution on YOUR website!
LET Y=+f%28x%29=+-x%5E2%2B4x-1+
GIVE DIFFERENT VALUES TO X IN THE ABOVE EQUATION AND FIND CORRESPONDING VALUES OF Y..TABULATE AS FOLLOWS,CHOOSE A SUITABLE SCALE AND PLOT THEM ON A GRAPH AS SHOWN BELOW
X....0.....1......2.....3.......4......ETC..
Y....-1....2......3.....2.......-1
+graph%28+600%2C+600%2C+-6%2C+6%2C+-10%2C+10%2C-x%5E2%2B4%2Ax-1%29+
