Question

Use the given domain to find the range
y=-2x+3 D: x is less then or equal to 0

Answer 1

Input interpretation:
f(x)=-2x+3 over the interval [0, infinity)

Lets say x=0, (and this is the largest value for -2x that we can get, since the rest of the x-values make it negative)

f(0)=-2(0)+3
f(0)= 3

So the greatest range is 3.

And the range approaches infinity closer and closer, the larger the x (the domain) gets.
