Consider the relation F defined by the equation y = 2x – 3, with domain {–1, 1, 2}. What is the range of F?
2 answers:
Answer:
(-5,-1,1)
Step-by-step explanation:
You must substitute for <em>x</em>.
Answer:
F(x) = 2x - 3
then
F(-1) = 2(-1) - 3 = -2 - 3 = -5
F(1) = 2(1) - 3 = 2 - 3 = -1
F(2) = 2(2) - 3 = 4 - 3 = 1
then
the range = {–5 , -1 , 1}
