I'm doing a copying figures geometry assignment can you me answer these questions!
1. a + b
2. a - b
3. 2b + a
4. a + b + c
5. a + 2b -c

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
