Select the correct answer.
does the equation below represent a relation, a function, both a relation and a function, or neither a relation nor a function?
y = 3: 2 – 93 + 20
a.
neither a relation nor a function
b. both a relation and a function
c.
function only
d.
relation only

A

Step-by-step explanation:

neither a relation nor a function

NOTE: This is the answer for the equation (y=3x^2-9x+20)                              Both a Relation and a Function

Step-by-step explanation:

Because a Relation can be represented as a verbal descriptions, graphs, mapping diagrams, equations, list ordered pairs, and tables. Which in this case is an equation so its a RELATION.

A function is a type of relation in which every x-value in the domain is paired with exactly one y-value. Which in this case every x-value is paired with one Y-value.

if you're trying to figure out how much each ounce cost it would be 0.20

cents each ounce

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)
