Question

I'm in high school and need help on Algebra Two homework. I need to know know how this is read: T:a-->a^2+3a+4. can anyone help??

Answer 1

this is a quadratic equation which graph is that of a parabola

Answer 2

it is a fancy way to write function notation, often seen as
\[f(x)=x^2+3x+4\]

Answer 3

\(T\) sends \(a\) to \(a^2+3a+4\)

Answer 4

T:a-->a^2+3a+4

means

T is a function rule that maps 'a' to a^2+3a+4

essentially f(a) = a^2 + 3a + 4 is the function rule that you may be familiar with in terms of notation

Answer 5

I need a little more detail like my first problem was f(x) and i had to write f of x. something like that. Would that be how you write it satellite73?

Answer 6

i am not sure what the actual question is
do you have something other than
\[T:a\to a^2+3a+4\]?

Answer 7

A(x)= 1/2x(5-x)

Answer 8

i guess i am not clear
my question is, what is your question ?
what are you supposed to do with this?

Answer 9

im supposed to tell how each is read

Answer 10

"A of x equal one half x times the quantity five minus x "
