The domain is the value of x. In this case, -3≤x≤7
the range is the value of y. in this case, -1≤y≤9

this is not a function, because the same x value has two corresponding y values. For example, when x=5, y=0 or y=8

It IS a function if every x value has only one corresponding y value.

Suppose that X ∼ N(−7, 14). Find the value of x for which P(|X + 7| ≤ x) = 0.44

grigory [225]

$\mathbb P(|X+7|\le x)=\mathbb P\left(\left|\dfrac{X+7}{14}\right|\le\dfrac x{14}\right)$
$=\mathbb P\left(|Z|\le\dfrac x{14}\right)=0.44$
$\implies\mathbb P\left(-7\le Z\le\dfrac x{14}\right)=0.22$
$\implies\mathbb P\left(Z\le\dfrac x{14}\right)=0.5+0.22=0.72$

$\implies\dfrac x{14}\approx0.5828$
$\implies x\approx8.1598$
