Answer:

$B.\:\: g(x)=4(2^x)$

Step-by-step explanation:

The given function is $f(x)=2^x$ .

If an exponential function is of the form; $F(x)=a(b^x)$ , then $0$ will vertically shrink the base function $f(x)=b^x$

and $a\:>\:1$ will vertically stretch the graph by $a$ units.

What is the inverse function for h(x) = <img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx%2B7%7D%20-1" id="TexFormula1" title="\sqrt

Blizzard [7]

Step-by-step explanation:

$y = \sqrt{x + 7} - 1$

Replace x and y.

$x = \sqrt{y + 7} - 1$

Solve for y.

$x + 1 = \sqrt{y + 7}$

Square both sides.

$(x + 1) {}^{2} = y + 7$

$(x + 1) {}^{2} - 7 = y$

This is the inverse function or you can also say

${x}^{2} + 2x - 6 = y$
