What is the "C" Value?
The c-value of the quadratic equation y = ax² + bx + c is the y-intercept.This determines where the parabola crosses the y-axis.
It can adjust how high or low the parabola rests on the y-axis, or in other words shift the parabola upwards and downwards.
The larger the c-value/ y-intercept, the higher up the parabola will lie on the y-axis.
ex: c= 5
The smaller the c-value/ y-intercept, the lower down the parabola will lie on the y-axis.
ex: C= -17

Example:
Equation 1- y= 6x² + 2x + 17
a= 6
b= 2
c = 17
Equation 2- y= -5x² + x - 3
a= -5
b= 1
c = -3
Equation 1 has a larger c-value -------> y-intercept= (0,17)
It will be higher up the y-axis
Equation 2 has a smaller c-value --------> y-intercept = (0, -3)
it will be further down the y-axis
a= 6
b= 2
c = 17
Equation 2- y= -5x² + x - 3
a= -5
b= 1
c = -3
Equation 1 has a larger c-value -------> y-intercept= (0,17)
It will be higher up the y-axis
Equation 2 has a smaller c-value --------> y-intercept = (0, -3)
it will be further down the y-axis
