Answer:
sqrt(8) units
Step-by-step explanation:
Use the formula d=sqrt((x2-x1)^2 + (y2-y1)^2). d=distance, and (x1, y1) and (x2, y2) are the points.
d=sqrt((4-2)^2 + (1-3)^2)
=sqrt(2^2 + (-2)^2)
=sqrt(4+4)
=sqrt(8)
A and B are sqrt(8) units apart.
sqrt(8) or 2.828
You use the distance formula which is sqrt((x2-x1)^2+(y2-y1)^2) where x2 can be either x value
b
f(7)=140
