The graph of the function, ƒ, is shown. find all numbers, x, such that f(x) = 1. a) ƒ(1) = 1, ƒ(2) = 1 b) ƒ(−1) = 1, ƒ(2) = 1 c) ƒ(1) = 1, ƒ(−2) = 1 d) ƒ(−1) = 1, ƒ(−2) = 1

You know that f(x) or y is 1, and you are trying to find all the numbers on the x-axis that has a y coordinate of 1. Based on the graph, when x is 2 and -1, the y coordinate is 1, so your answer is B.

B.

Step-by-step explanation:

We have been given graph of a function. We are asked to find all values of x, such that .

To solve our given problem, we need to find the values of x, when .

Upon looking at our given graph, we can see that at and , the value of the given function is 1, therefore, and option B is the correct choice.
