Question

Find the range of the function.

Answer 1

equation of the line passing through two points

we can chose two points from the graph

I took (5,0) and (0,5)

x-x1/x2-x1=y-y1/y2-y1

x-5/0-5=y-0/5-0

(x-5)*5=y*(-5)

x-5=-y

y+x=5

Explanation:

range of the function is [- infinite, infinite]

if x is determined as R number then even range of the function will be R ,real numbers.
