Consider the relation F defined by the equation y = 2x – 3, with domain {–1, 1, 2}. What is the range of F?

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}

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
