It looks like it’s already answered I’m confused about that
Answer:
Part A) The graph in the attached figure
Part B) see the explanation
Step-by-step explanation:
Part A) Graph the function
we have the quadratic function
![y=3x^2-12x-36](https://tex.z-dn.net/?f=y%3D3x%5E2-12x-36)
This is a vertical parabola open upward
The vertex is a minimum
using a graphing tool
The graph in the attached figure
Part B) What are the values of a, b and c?
we know that
The values of a and b represent the x-intercepts of the quadratic equation
The x-intercepts are
(-2,0) and (6,0)
so
![a=-2\\b=6](https://tex.z-dn.net/?f=a%3D-2%5C%5Cb%3D6)
Find the value of c
we know that
The x-coordinate of the vertex in a vertical parabola is equal to the midpoint of the roots
so
The value of c is equal to
![c=\frac{a+b}{2}](https://tex.z-dn.net/?f=c%3D%5Cfrac%7Ba%2Bb%7D%7B2%7D)
substitute the given values
![c=\frac{-2+6}{2}=2](https://tex.z-dn.net/?f=c%3D%5Cfrac%7B-2%2B6%7D%7B2%7D%3D2)
see the attached figure
Answer: 1⁷/₈ pounds
Step-by-step explanation:
The weight of the whole melon is the sum of the 1¹/₈ pounds given to the neighbor and the 6/8 pounds remaining.
Convert improper to proper:
1¹/₈ = 9/8
= 9/8 + 6/8
= 15/8
= 1⁷/₈ pounds
