The graph of g(x) is the result of translating the graph of f(x) = three units to the left. What is the equation of g(x)?
jenyasd209 [6]
In the case of exponential functions, the graph is shifted when a constant is added to the exponent of the constant. The original equation, f(x) is:
f(x) = (1/2)ˣ
Now, when horizontal shifting is occurring, the equation is:
y = Cˣ⁺ᵃ
If a is positive, the graph shifts to the lefts and the shift is equal to a units. If a is negative, the graph shifts to the right and the shift is equal to a units. Therefore, to shift the graph 3 units to the left:

g(x) = (1/2)⁽ˣ⁺³⁾
The correct answer is B.

In the year 1998, the surface elevation of Lake Powell was 3881 feet above sea level. In the year 2006, the surface elevation of
Vesna [10]

The surface elevation of Lake Powell is decreasing at the rate of 77.2 feet per year.

<h3>What is the rate(slope) at which the sea is decreasing?</h3>

The rate at which the surface elevation of the Lake Powell is decreasing can be determined by calculating the slope(steepness) of the sea.

The slope can be given as:

Slope (Δm) = rise/run

Slope (Δm)  = Δy/Δx

slope (Δm)  = y₂ - y₁/x₂-x₁

slope (Δm)  = 3263.4 - 3881/2006-1998

slope (Δm)  = -617.6/8

slope (Δm)  = -77.2

Therefore, we can conclude that the surface elevation of Lake Powell is decreasing at the rate of 77.2 feet per year.

Solve for x: 0.4x - 3 = 1.4
vlabodo [156]

Answer: x = 11

Step-by-step explanation:

First, add 3 to both sides

0.4x - 3 = 1.4

        +3    +3

0.4x = 4.4

Then, divide each side by 0.4 to isolate x

x = 11
