Question 16
Complete the table of values for y=x2+3x−2y = x^2 + 3x - 2y=x2+3x−2
| xxx | -4 | -3 | -2 | -1 | 0 | 1 | 2 |
|---|---|---|---|---|---|---|---|
| yyy | 2 | -4 | 2 |
a.[4]
On the grid draw the graph of y=x2+3x−2y = x^2 + 3x - 2y=x2+3x−2 for values of x x\,x from -4 to 2
b.[2]
Use the graph to find estimates of the solutions to the equation x2+3x−2=−1x^2 + 3x - 2 = -1x2+3x−2=−1
