Can someone me with the ones that are circled?

you so much greatly appreciated : )

3.) f(x)=-2(x+1)^2+3

Domain: (- infinity, infinity)

Range:(-infinity,3]

Vertex: (-1,3)

Axis of symmetry: x=-1

Opens downward

4.) f(x)=9(x-2)^2-3

D:(-infinity, infinity)

R: [-3,infinity)

Vertex: (2,-3)

Axis: x=2

Opens upward

6.)

D:(-infinity, infinity)

R:(-infinity,0]

Vertex: (5,0)

Axis: x=5

Opens downward

answer: i don't understand it

step-by-step explanation: sorry

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
