If the graph of quadratic polynomial ax2 + bx + c cuts negative direction of y-axis, then what is the sign of c?
If quadratic polynomial ax2 + bx + c cuts Negative direction of y-axis, then it means that the value of y is negative when x = 0 [∵ at y-axis, x = 0]
y = c at x = 0 and y is Negative.
So, c is Negative.
