All points of the step function f(x) are graphed. On a coordinate plane, a step graph has horizontal segments that are each 1 unit long. The left end of each segment is a closed circle. The right end of each segment is an open circle. The left-most segment goes from (negative 3, 1) to (negative 2, 1). Each segment is 1 unit lower and 1 unit farther to the right than the previous segment. The right-most segment goes from (0, negative 2) to (1, negative 2). What is the range of f(x)? −3, −2, −1, 0, 1 −2, −1, 0, 1 all real numbers such that −3 < y ≤ 1 all real numbers such that −2 < y ≤ 1

Demonstrate the proof of your new polynomial identity through an algebraic proof and a numerical proof in an engaging way! make it so the whole world wants to purchase your polynomial identity and can't imagine living without it! you must: label and display your new polynomial identity prove that it is true through an algebraic proof, identifying each step demonstrate that your polynomial identity works on numerical relationships create your own using the columns below. see what happens when different binomials or trinomials are combined. square one factor from column a and add it to one factor from column b to develop your own identity. column a column b (x − y) (x2 + 2xy + y2) (x + y) (x2 − 2xy + y2) (y + x) (ax + b) (y − x) (cy + d)

Need on this one asap im almost done with this subject

When you answer this can you explain
