Vertex represents a maximum or minimum point for the function. Explain your
1 answer:
Answer:
the vertex represents a maximum
Vertex is (4,7)
f(x)=-(x-4)^2+7
Step-by-step explanation:
Given the function
Equation is in the form of y=ax^2+bx+c
When 'a' is negative, then vertex is maximum
when 'a' is positive, then vertex is minimum
is negative, so the vertex represents a maximum
, factor out negative
Take out negative sign in common

Rotation being a rigid transformation, does not alter the angle and side lengths after transformation.
The arrow in Figure B will have the same angle measure as Figure A
From the complete question (see attachment), we understand that:
Figure A is rotated 90 degrees clockwise around point (2,2)
Rotation is a rigid transformation
This means that: after the transformation
- Figure A and figure B will have the same side lengths
- Figure A and figure B will have the same measure of angles
The above highlights imply that, the arrow in Figure B will have the same angle measure as Figure A
