3(n - 1) = 5n + 3 - 2n
3n - 3 = 3n + 3
3n - 3n = 3 + 3
0 = 3 ...(incorrect)

Jeremy and Arnold are working on a project for math class in which they are to identify the quadratic equation that represents a
denis23 [38]

Answer:

The parabola generated by the expression :

y=x^2-2x+3

is the one that better represents a rain gauge above the ground.

Step-by-step explanation:

The function:

a) y=x^2+11x+24

Direction of parabola: branches pointing up

Location of vertex relative to x-axis: below

So, the parabola doesn't depict a rain gauge off the ground

b) y=-x^2-6x-8

Direction of parabola: branches pointing down

Location of vertex relative to x-axis: above

So, the parabola doesn't depict a rain gauge off the ground

c) y=x^2-2x+3  

Direction of parabola: branches pointing up

Location of vertex relative to x-axis: two units above

So, the parabola depicts a rain gauge off the ground

d) y=x^2+4x+4

Direction of parabola: branches pointing up

Location of vertex relative to x-axis: right on the x-axis

So, the parabola doesn't depict a rain gauge off the ground (this is sitting on the ground)

e) y=3x^2+21x+30

Direction of parabola: branches pointing up

Location of vertex relative to x-axis:  below

So, the parabola doesn't depict a rain gauge off the ground
