SOLUTION: Using scale of 2cm toi represnt 1unit of the ×-axis and 2cm toi represnt 5unit onthe y-axis,draw thé graph of y=×²+3×-1 for values of ×in thé range -4≤×≤3 a) from you

Question 1187091: Using scale of 2cm toi represnt 1unit of the ×-axis and 2cm toi represnt 5unit onthe y-axis,draw thé graph of y=×²+3×-1 for values of ×in thé range -4≤×≤3
a) from your graph détermine thé value of× for which y=2.5
b) by drawing asuitable straightline find thé solution toi thé équation ×²+2×-3=0
