Rewrite the equation as ax2 +bx+ c = y a x 2 + b x + c = y. ax2 + bx+c = y a x 2 + b x + c = y Move y y to the left side of the equation by subtracting it from both sides. ax2 + bx+c−y = 0 a x 2 + b x + c - y = 0
How do you solve ax2 + bx+c?
Rewrite the equation as ax2 +bx+ c = y a x 2 + b x + c = y. Move y y to the left side of the equation by subtracting it from both sides. Use the quadratic formula to find the solutions.
How do you find the value of y=ax2+bx+c?
The parabola y=ax 2+bx+c cuts Y-axis at P which lies on OY. Putting x = 0 in y=ax 2+bx+c, we get y = c.
How do you find the equation of a graph?
Also, notice that now the equations for the graphs are the normal linear equations of the form y = m x + b, where m is the slope and b is the y-intercept. Example 3: Let a = 1 and c = 0.
How to find the direction the graph opens towards?
How to Find the the Direction the Graph Opens Towards y = ax2 + bx + c Our graph is a parabola so it will look like or In our formula y = ax2 + bx + c, if the a stands for a number over 0 (positive number) then the parabola opens upward, if it stands for a number under 0 (negative number) then it opens downward. 6.
