Function Notation
When $3$ is the input for the function $f$, what is the output?
When $a$ is the input for the function $f$, what is the output?
When $x^2+1$ is the input for the function $g$, what is the output?
When the output is $h\left(5\right)$, what was the input?
When the output is $T:x^2⟼$, what was the input?
Example
For this function, $f\left(x\right)=$
For this function, $f:x⟼$
$f\left(1\right)=$
$f\left(2\right)=$
$f\left(-3\right)=$
$f\left(\frac{3}{2}\right)=$
$f\left(-4.5\right)=$
$f\left(x^2\right)=$
$f\left(x+1\right)=$
$f\left(a+b\right)=$
