Answer:
D) Plane
Step-by-step explanation:
A rectangular prism is a six sided figures. Each side is represented by a plane.
Each side has two measures, length and width. So it is presented by a plane.
Therefore, the answer is D) Plane
B) x^2 + 9x – 2
C) 16x^2 + 4x – 6
D) 4x^2 + 20x – 2
The value for the compositefunction is 4x² + 20x - 2.
Option D is the correct answer.
A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
To find (C o D)(x), we need to substitute d(x) into c(x) and simplify the resulting expression.
First, we have:
C(D(x)) = 4D(x) - 2
Next, we substitute d(x) for x in the expression for D(x):
D(x) = x² + 5x
So,
C(D(x)) = 4(x² + 5x) - 2
Simplifying, we get:
C(D(x)) = 4x² + 20x - 2
Therefore,
The value for the compositefunction is 4x² + 20x - 2.
