Explanation:

<h3>Part 1.</h3>

The inverse of a function y = f(x) can be found by solving x = f(y) for y.

When we do that here, we find ...

  x=f(y)\\\\x=\dfrac{y+a}{b}\\\\bx=y+a\\\\y=bx-a

When we compare this to g(x), which we want to be the inverse of f(x), we see that ...

  cx -d = bx -a   ⇒   b=c, and d=a

We can choose a=d=1 and b=c=2 to make the two functions inverses:

  f(x) = (x +1)/2

  g(x) = 2x -1

__

<h3>Part 2.</h3>

The inverse of f(x) is g(x) if f(g(x)) = x.

  f(g(x)) = ((2x -1) +1)/2 = 2x/1 = x . . . . . g is the inverse of f

__

<h3>Part 3.</h3>

Same as Part 2, but in reverse.

  g(f(x)) = 2((x +1)/2) -1 = (x +1) -1 = x

__

<h3>Part 4.</h3>

The attachment is a graph of the two functions and a table of values. The line y=x is the dashed orange line. You will notice that f(x) and g(x) are reflections of each other across that line.

What can you say about the y-values of the two functions <img src="https://tex.z-dn.net/?f=f%28x%29%20%3D%203%5Ex-3" id="TexForm
slavikrds [6]

Answer:

a) The minimum y-value of f(x) is -3

d) The minimum y-value of g(x) is -3

Step-by-step explanation:

Given in the question that,

f(x) = 3^{x}-3

g(x) = 7x² - 3

<h3>A)</h3>

At large negative exponents, the value approaches to zero

y = 3^{-100}-3=-3

y = 3^{-1000}-3=-3

y = 3^{-10000}-3=-3

<h3>B)</h3>

Minimum y-value of g(x) will be when x = 0

y = 7x² - 3

y = 7(0) - 3

y = -3

The population of a city in 2005 was 18,000. By 2010, the city’s population had grown to 45,000. Economists have determined that
SpyIntel [72]
Exponential model is y=Ae^(kt)
Assume initial start is 2005, time = 0, so y = 18000e^(kt)
45000 = 18000*e^(k5)
solve for k, approx 0.1832
y = 18000*e^(1.832) = 112,435, approximately
