What measures of center and spread are best used if the data is symmetrical and asymmetrical? Explain your reasoning

Y=4x^2+x-1 solve using quadratic formula

1. what is the formula for finding the vertical distance between two points on a coordinate plane?

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3
