A quadratic function yields the following values:
х
y
-4
1
-3
-5
-2
-7
-1
-5
0
1
Which of the following is the equation for the function?
O A. y = –6x2 + 1
O B. y = – 2x² - 721
OC. Y = 3.x2 + 9x - 11
o D. y= 2x² + 8x - 1
answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
Create and solve a linear equation that represents the model, where squares and triangles are shown evenly balanced on a balance beam. assume the weight of a square is 1 unit and the weight of a triangle is unknown.
