The equation for the parabola is y = (5/3)(x + 2)(x - 1.2)
A mathematical statement that has a "equal to" symbol between two expressions with equal values is called an equation. as in 3x + 5 Equals 15, for instance. Equations come in a variety of forms, including linear, quadratic, cubic, and others. In this tutorial, let's study more about mathematical equations.
Remove parentheses from each side of the equation and combine similar terms to make it simpler.
To separate the variable term on one side of the equation, use addition or subtraction.
To find the variable, use division or multiplication.
y = A [x - (-2)] (x - 1.2)
y = A(x + 2)(x - 1.2)
At the y-intercept,
-4 = A(0 + 2)(0 - 1.2)
-4 = -2.4A
A = 4/2.4 = 5/3
y = (5/3)(x + 2)(x - 1.2)
