The graph of the quadratic function \(y = ax^2 + bx + c \) has a minimum turning point when \(a \textgreater ... Draw the graph of \(y = x^2 -x – 4 \) and use it to find the roots of the ...

Save guides, add subjects and pick up where you left off with your BBC account. To find solutions from graphs, look for the point where the two graphs cross one another. This is the solution point.
