Nina mixed 2 ⅛ pounds of apples, 1 ½ pounds of berries, and 1 ¼ pounds of grapes for a salad. She set aside ⅓ of the slad for dinner and put the rest in a container for later. How many pounds of salad did she put in the container?

Step-by-step explanation:

Given

Nina mixed pounds of apples, pounds of berries, and pounds of grapes.

Total salad is

Now, one-third of the salad is kept aside and the remaining is put in the container.

Amount of salad Put in the container is

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
