Answer:

18+2x

Step-by-step explanation:

Let the number be x.

Translate: 2x + 18 = x - 4.

Subtract x from each side: x + 18 = -4.

Subtract 18: x = -22.

Check: 2(-22) + 18 = -44 + 18 = -26; -22 - 4 = -26.

Answer:

In a nutshell, $g(x) = x+2$ .

Step-by-step explanation:

A composition is operation between function that consist in replacing the independent variable of the first function, $f(x)$ in this case, for $g(x)$ . Common notations for composition between functions are $f(g(x))$ and $f\circ g (x)$ . If we know that $h(x) = f\circ g (x) = (x+2)^{2}$ and $f(x) = x^{2}$ , then $g(x) = x+2$ .
