The graph of a curve that passes the vertical line test is known as a function. Functions are graphical representations that may have multiple x-values for a given y-coordinate, but will never have multiple y-values for any given x-coordinate.

Answer:

(c) 3
Step-by-step explanation:
Given polynomial :
f(x) = 2x³–5x² + 5x
Let the number to be subtracted be n
(x is already in equation so, n is better)
since, 2x – 3 factor given
→

So,


Answer:The number of days it will take to sell the same amount of cookies is 3 and the number of tubs that will be sold is 27
Step-by-step explanation:
Let x represent the number of days it will take either of them to sell the same number of tubs.
Let y represent the total number of tubs that that Joseph will sell in x days.
Let z represent the total number of tubs that that Dwayne will sell in x days.
Joseph has already sold 3 tubs. If Joseph starts selling 8 tubs per day, it means that in x days, the number of tubs that he will sell will be
y = 8x + 3
Dwayne hasn't sold any yet. If Dwayne begins selling 9 tubs per day, it means that in x days, the number of tubs that he will sell will be
z = 9x
To determine the number of days it will take to sell the same amount of cookies, we will equate y to z. It becomes
8x + 3 = 9x
9x - 8x = 3
x = 3
The number of tubs that each will sell will be 9x = 9×3 = 27
