O-12
0 3

Answer 1

Explanation:

you do know how functions work ?

you define a continuous function typically by an expression using at lest one variable.

then, when we know the value of the variables to be used in that function, we put these values into the place of the variable(s) and simply calculate :

f(x) = x² + x

so,

f(-3) = (-3)² + (-3) = 9 - 3 = 6
