Question

(a) If f(x)= x2
and domain = {-1,0,1), then find the range

​

Answer 1

Answer:

{0, 1}

Step-by-step explanation:

We determine the range of any function in a definite/fixed domain. Here, it is {-1, 0, 1}. So, we would conclude the different-different values of y(or range) for each value of x.

When x = - 1:

 f(x) = (-1)² = 1

When x = 0:

 f(x) = 0² = 0

When x = 1:

  f(x) = 1² = 1

There are only two outcomes(0 and 1) therefore, range of the given function is {0, 1}
