The graph of the quadratic function \(y = ax^2 + bx + c \) has a ... Draw the graph of \(y = x^2 -x – 4 \) and use it to find the roots of the equation to 1 decimal place. Draw and complete ...

From the graph, we can also see that the y-intercept is 6, therefore we can say that the equation of the straight line is \(y = mx + 6\). Now we need to find the gradient.
