Question

function notations For the function below for which values of x does f (x)=3 ?

Answer 1

Answer:

x = 2

Explanation:

Each ordered pair in the function has the form (x, f(x)). So, the first coordinate is x and the second coordinate of each pair is f(x).

Then, the ordered pair that has a second coordinate equal to 3 or f(x) = 3 is the pair (2, 3). Therefore, the value of x that does f(x) = 3 is x = 2

So, the answer is x = 2
