The graph shows the translation, g(x), of the function f(x). What integer represents the horizontal translation of f(x) to g(x)?
1 answer:
The integer that represents the horizontal translation of f(x) to g(x) is 4
<h3>How to determine the integer?</h3>The attached graph represents the missing piece in the question
From the graph, we can see that:
The function g(x) is 4 units to the left of the function f(x)
This means that:
g(x) = f(x + 4)
Hence, the integer that represents the horizontal translation of f(x) to g(x) is 4

The mass of the wire is found to be 40π√2 units.
<h3>How to find the mass?</h3>To calculate the mass of the wire which runs along the curve r ( t ) with the density function δ=5.
The general formula is,
Mass =
To find, we must differentiate this same given curve r ( t ) with respect to t to estimate |r'(t)|.
The given integration limits in this case are a = 0, b = 2π.
Now, as per the question;
The equation of the curve is given as;
r(t) = (4cost)i + (4sint)j + 4tk
Now, differentiate this same given curve r ( t ) with respect to t.
Further simplifying;
Now, use integration to find the mass of the wire;
Therefore, the mass of the wire is estimated as 40π√2 units.
