Question

f(x) = x2 - 5
For the function shown, what is the range of the function when the domain is {2, 4, 7}?

Answer 1

Note: Please write "the square of x" as x^2. x2 is incorrect (and vague).

f(x) = x^2 - 5

Answer 2

Hint: What are the three y-values obtained when letting the x values be {2, 4, 7}?

Answer 3

Hint: Think of what the question is asking and listen to the ranges when you are given the x-values. I hope you find your answer.
