Question

The graph of the function, ƒ, is shown. Find all numbers, x, such that f(x) = 1.

Answer 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.

Answer 2

Answer:

B. $f(-1)=1,f(2)=1$

Step-by-step explanation:

We have been given graph of a function. We are asked to find all values of x, such that $f(x)=1$.

To solve our given problem, we need to find the values of x, when $y=1$.

Upon looking at our given graph, we can see that at $x=-1$ and $x=2$, the value of the given function is 1, therefore, $f(-1)=1,f(2)=1$and option B is the correct choice.
