Which of the following equations describes the graph?

Mathematics

Artist 52 [7]3 years ago

Answer:

y = 1/2x^2 - 2x + 1

Step-by-step explanation:

The equation of the parabola in vertex form is y = 1/2 (x - 2)^2 - 1. By finding the vertex at (2,-1) we plug in the point into the formula y = a(x-h)^2 + k. To convert it to standard form like the equations listed, multiply through the distributive property to clear the parenthesis.

y = 1/2 (x-2)(x-2) - 1

y = 1/2 (x^2 - 4x + 4) - 1

y = 1/2x^2 - 2x + 2 - 1

y = 1/2x^2 - 2x + 1

SpyIntel [72]
That technique for solving equations is: Whatever you do to one side of the equation, you have to do to the other side to preserve the equality The technique for solving inequalities is: Whatever you do to one side of the inequality, you have to do to the other side to preserve the inequality. the techniques are the same. The difference between solving equations and solving inequalities is: If you multiply or divide an inequality by a negative number, then the inequality reverses. !!!!!

PLEASE HELP, WILL MARK AS BRAINLIEST!!!!!!!!!!!
Lisa [10]

A Trapezoid needs to have one pair of sides parallel.

Two of the points already plotted have the same Y value ( 3)

So the 4th dot, should have the same Y value as the first dot, which is 1.

The 4th dot should be plotted at C (5,1)
