Can someone solve this with an explanation?

Step-by-step explanation:
The domain is the set of x-values used as inputs for the given function. The f(x) represents the output, which is the resulting set of all values taken on by the dependent variable. Since you're given the function, f(x) = x², it simply means that you take your x-values, and use them as inputs for the function.
f(x) = x²
f(x) = (-2)² = 4
Therefore: x = -2, f(x) = 4. (x, f(x)) = (-2, 4).
f(x) = (-1)² = 1
Therefore: x = -1, f(x) = 1. (x, f(x)) = (-1, 1).
f(x) = (0)² = 0
Therefore: x = 0, f(x) = 0. (x, f(x)) = (0, 0).
f(x) = x²
f(x) = ( 1 )² = 1
Therefore: x = 1, f(x) = 1. (x, f(x)) = (1, 1).
f(x) = x²
f(x) = (2)² = 4
Therefore: x = 2, f(x) = 4. (x, f(x)) = (2, 4).
Answer:
Just substitute for x = -2 f(x)= (x)^2 we substitute (-2) ^2 =-2 *-2 = 4 if you use brackets like the example you will have no issues For x f(x) = -2 and 4 so thats the first question done hope the formula helps
