Answer:
Step-by-step explanation:
To obtain the inverse of f(x)
let y = f(x) and rearrange making x the subject, that is
y = 2x - 1 ( add 1 to both sides )
y + 1 = 2x ( divide both sides by 2 )
= x
Change y back into terms of x with x = (x) , thus
(x) =
Evaluate g(3) and substitute the value obtained into (x)
g(3) = 3² + 1 = 9 + 1 = 10, then
(10) = =
Answer:
The answer is X=11 and X=-11
Answer:
Hi, There!
Part A: tell me the Characteristics of a Reflection
There are several important characteristics of a reflection:
- A reflection maps a line to a line, a ray to a ray, a segment to a segment, and an angle to an angle. Each piece of the original pre-image is exactly the same in the image.
- A reflection preserves lengths of segments. The length of a line segment will be the same in a reflection.
- A reflection preserves degrees of angles. The angles of the image are congruent to the angles in the pre-image.
Part B:
Rigid transformation: Moving a figure so that it is in a new location but has the same size, shape, and area. A mathematical reflection is a type of rigid transformation
Part C:
what is Line of reflection: The line over which a pre-image is reflected to create a new image
Answer:
Step-by-step explanation:
13. -2(4)= -8 14. 6(-5)= -30 15. 3(-5)(2)= -30
16. -12(4)= -48 17. -4(2)^2= -64 18. (-5)^2= -25
19. -5(-3)(4)= =60 20. 13(-5)(2)= -130. 21. 3(-3)= -9
Hope this helps!
