Which exponential function is represented by the values in the table?

svlad2 [7]

Here we use the equation

$y = a(b)^x$

Taking points (0,4), (1,2)

Substituting the point (0,4) , we will get

$4 = a(b)^0
\\
4 = a(1) \\
a =4$

Substituting (1,2) we will get

$2 = 4 (b)^1
\\
2/4 = b
\\
b = 1/2$

So we have

$a = 4, b = 1/2$

Therefore , required equation is

$y = 4(1/2)^x$

In the function f(x)=(x-2)^2+4, the minimum value occurs when x is

Vinil7 [7]

The graph of the function is a parabola.

The nose comes down as far as y=4 but no farther.

That happens when (x - 2)² = 0 , and THAT happens when x = 2 .

Wendall designs a tower with a height in feet that can be represented by the function T(x) = 9(x + 6.9), where x is the height o

Vinil7 [7]

Answer:

$G(T(x)) = 27(x + 6.9)$

Step-by-step explanation:

Given

$T(x) = 9(x + 6.9)$

$G(x) = 3x$

Required [Missing from the question]

G(T(x))

We have:

$G(x) = 3x$

This implies that:

$G(T(x)) = 3(T(x))$

Substitute: $T(x) = 9(x + 6.9)$

$G(T(x)) = 3[9(x + 6.9)]$

Open bracket

$G(T(x)) = 27(x + 6.9)$
