For a graph to be considered PROPORTIONAL it has to do what 2 things?Immersive Reader (2 Points)

The answer that i got was 8/3

answer: you need to organize this better it does not make sense.

step-by-step explanation: ?

see attached

step-by-step explanation:

given the function as;

[tex]f(x)=2x^3-7x^2+2x+3[/tex]

write the equation replacing f(x) with y

[tex]y=2x^3-7x^2+2x+3[/tex]

form and fill a table containing values of y with corresponding values of x

you can take a range for values of x as -3≤x≤3

solving for x=-3

[tex]f(-3)=2*-3^3-7*-3^2+2*-3+3=2*-27-63+-6+3=-54-63-6+3y=-120[/tex]

for x=-2

[tex]f(-2)=2*-2^3-7*-2^2+2*-2+3=2*-8-28+-4+3=-16-28-4+3=-45[/tex]

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values of x and obtain the following graph

For a 0.25 pfor b o.3pp (0.25+0.3)=0.28
