The domain for f(x) and g(x) is the set of all real numbers. let f(x) = 2x^2 + x − 3 and g(x) = x + 2. find (f • g)(x).

Composing two functions means to use the output of one as the input of the others. In fact, you can write the composition as

and then compute both functions, from inside outwards:

And maybe it's a good idea to simplify the expression: expand the square to get

sum like terms:

answer: the answer to your question is parallel

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
