Which graph represents a functionThe set of ordered pairs (–1, 8), (0, 3), (1, –2), and (2, –7) represent a function. What is the range of the function? {x: x = –1, 0, 1, 2} {y: y = –7, –2, 3, 8} {x: x = –7, –2, –1, 0, 1, 2, 3, 8} {y: y = –7, –2, –1, 0, 1, 2, 3, 8}

The length of triangle base is 26. a line, which is parallel to the base divides the triangle into two equal area parts. find the length of the segment between triangle legs.

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (–4, 0) and (6, 0). the y-intercept of the first parabola is (0, –12). the y-intercept of the second parabola is (0, –24). what is the positive difference between the a values for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth
