The distance from the origin to the point (-20, 21) is

For this case we have that by definition the distance between two points is given by:

Where we have the points are given by:

Substituting values we have:

The distance from the origin to the point (-20, 21) is:

d = 29

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
