What is the value of -2x squared + 4y if x =-2 and y = 3

The value is:

Step-by-step explanation:

You have the following expression:

The exercise provides you these values of the variables "x" and "y":

Then, in order to find the value of  , you need to substitute the given values of the variables into the expression.

Therefore, its value is:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

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

for x=-2

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
