| **The graph of the quadratic function y = −9.5×2 + 14 intersects the y-axis at point F. Determine the unknown coordinate of the point F (0; y).**

To find the unknown coordinate y at point F, you need to calculate the value of the expression y = -9.5×2 + 14 for x = 0:

y = -9.5 * 0 ^ 2 + 14 = 0 + 14 = 14;

Point F has coordinates (0; 14).

Answer: the unknown coordinate of the point of intersection of the y-axis by the graph of the function is 14.
