plot the equation 3x2+9x-6y+18=0 of the parabola.
Without an equality sign it can not be considered to be an equation and the - or + value of 9x has not been given
It is an up parabola.
-3x2+12x-1 = y Solve the quadratic equation when y = 0 by means of the quadratic equation formula which gives x values of 3.914854216 and 0.085145784. Add these values together and divide them by 2 which is 4/2 = 2 and this is the line symmetry of the parabola. Substitute 2 for x into the original equation to find the value of y: So the vertex is at (2, 11) Remember that the parabola has a maximum value because the coefficient of x2 is negative in other words it will face downwards.
Vertical line of symmetry cuts through x = -4 - (sqrt of 3)
Set the equation equal to zero. 3x2 - x = -1 3x2 - x + 1 = 0 The equation is quadratic, but can not be factored. Use the quadratic equation.
It is not an equation it is an expression but if it was in the form of 4-x-3x2 = 0 then 3x2 by itself:- 3x2 = 4 -x
Yes. (Assuming that -3x2 is the best representation of 3x2 that this browser will allow.)
an upside down parabola
