Help me pls anything helps

Step-by-step explanation:

This is a function as there is only one unique value of y for any unique value of x. It passes the ‘vertical line test’.

So insert ‘F’ as this is a function.

F

Step-by-step explanation:

this is a function because it is just a reflection over the x-axis

the function is f(x) = -(x - 1)^2 + 3

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
