Answer:-
To find the y-intercept of a quadratic function, you simply set ???? = 0 x=0 and solve for ???? y. In a quadratic function of the form ???? = ???? ???? 2 + ???? ???? + ???? y=ax 2 +bx+c, substitute ???? = 0 x=0 into the equation. This eliminates the terms with ???? x, leaving you with ???? = ???? y=c. The y-intercept is the point where the graph of the quadratic function crosses the y-axis, so the value of ???? c represents the y-intercept. This process works for any quadratic equation, whether it's in standard or vertex form.
