Simplify the expression by combining like terms. -8x - 4x -12x 32x -12 + x -4x simplify the expression by combining like terms. -6y + 6 - 4 + 2 + y -4 -5y -5y - 1 -7y + 1 -7y simplifying 3y + 2x + 4 + y - x by combining like terms is equivalent to 4y + 3x + 4 true or false.

Equation of parabola is :

Step-by-step explanation:

Given,

x = -2  0  4

f(x) = 4  -6  70

General equation of parabola is:

Now we plug corresponding x and y values to get coefficient a,b and c.

Fro x =-2  and y( =f(x) ) = 4

        ______(1)

For x = 0 , y = -6

  _____(2)

For x = 4 , y = 70

  _____(3)

Plug c= - 6 in equation (1) and (3)

We get,  

solving above two equations to find a and b.

Multiply equation (1) by 2 then add equation (1) and (3)

Hence equation of parabola is :
