Find f(-2) if
y = x2-x-2

y = -4

Step-by-step explanation:

All you need to do is substitute -2 in for the x's in the equation. This gives you

y = -2(2) + 2 -2

y = -4

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
