After a shipwreck, Gary is stranded on a desert island. He needs to build a shelter, so he makes an axe using materials from the wreckage and starts cutting down trees. There is a proportional relationship between the number of days Gary is stranded on the island, x, and the total number of trees he cuts down, y. x (days) y (trees) 8 N 3 12 4 16 5 20 Write an equation for the relationship between x and y. Simplify any fractions. y = Submit

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

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)

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.
