If graph of quadratic polynomial ax2 + bx + c cuts positive direction of y-axis, then what is the sign of c?

Positive

If quadratic polynomial ax2 + bx + c cuts positive direction of y-axis, then it means that the value of y is positive when x = 0 [∵ at y-axis, x = 0]


Now


y = c at x = 0 and y is positive.


So, c is positive.
