The image of the point (1, 2, 3) is (3, 7)
<h3>How to determine the image?</h3>
The given parameters are:
- Point = (1, 2, 3)
- Transformation rule = (3x, 2y + z)
In (1, 2, 3), we have:
x = 1; y = 2 and z = 3
When the rule is applied, we have:
Image = (3x, 2y + z)
Image = (3 * 1, 2 *2 + 3)
Evaluate
Image = (3, 7)
Hence, the image of the point (1, 2, 3) is (3, 7)

Explanation:
For a function ...
y = f(x)
the inverse function is ...
x = f(y)
To write that in the form y=f^-1(x), you need to solve for y.
__
For your function f(x) = e^x +3 this looks like ...
x = e^y +3
x -3 = e^y . . . . . subtract 3
ln(x -3) = y . . . . . take the natural log
So, we can write ...
f^-1(x) = ln(x -3)
_____
Attached is a graph of these functions. As you might guess from the interchange of x and y, a function and its inverse are mirror images of each other across the line y=x.
Answer:
C
Step-by-step explanation:
Answer:
18%
Step-by-step explanation:
The computation of the percentage of the total fixed costs per unit is shown below:
= Total fixed cost ÷ Total cost
where,
Total fixed cost = Fixed manufacturing overhead + administrative salaries
= $12 + $24
= $36
And, the total cost is $200
So, the percentage of the total fixed costs per unit is
= $36 ÷ 200
= 0.18 or 18%
