Answer:
Option 3 3 1/8x - 6 3/10
Step-by-step explanation:
(3 1/2x - 4 1/10) - (3/8x + 2 1/5)
Divide it into parts:
(3 1/2x - 3/8x) + (-4 1/10 - 2 1/5)
3 1/2x - 3/8x = 3 4/8x - 3/8x = 3 1/8x
-4 1/10 - 2 1/5 = -4 1/10 - 2 2/10 = -6 3/10
So we get:
2 1/4x - 6 3/10
The function represents a reflection of f(x) = 5(0.8)x across the x-axis is f(x) = -5(0.8)^x
<h3>Reflection of functions and coordinates</h3>
Images that are reflected are mirror images of each other. When a point is reflected across the line y = x, the x-coordinates and y-coordinates change their position. In a similar manner, when a point is reflected across the line y = -x, the coordinates <u>changes position but are negated.</u>
Given the exponential function below
f(x) = 5(0.8)^x
If the function f(x) is reflected over the x-axis, the resulting function will be
-f(x)
This means that we are going to negate the function f(x) as shown;
f(x) = -5(0.8)^x
Hence the function represents a reflection of f(x) = 5(0.8)x across the x-axis is f(x) = -5(0.8)^x
