Question

Use the mapping shown above to show the value of the function ƒ(x) at each point.Question options:A) ƒ(1) = 5, ƒ(0) = 3, ƒ(1) = 5, ƒ(2) = 11, ƒ(3) = 21B) ƒ(–1) = 5, ƒ(0) = 3, ƒ(1) = 5, ƒ(2) = 11, ƒ(3) = 21C) ƒ(–1) = 5, ƒ(0) = 3, ƒ(1) = 5, ƒ(2) = 21, ƒ(3) = 11D) ƒ(5) = –1, ƒ(3) = 0, ƒ(5) = 1, ƒ(11) = 2, ƒ(21) = 3

Answer 1

B) ƒ(–1) = 5, ƒ(0) = 3, ƒ(1) = 5, ƒ(2) = 11, ƒ(3) = 21

Step-by-step explanation:

The domain of a function refers to all the inputs for which the function is valid

The range of a function refers to all the outputs obtained from the domain

From the picture, we were given the following mappings:

`\begin{gathered} f(-1)=5 \\ f(0)=3 \\ f(1)=5 \\ f(2)=11 \\ f(3)=21 \end{gathered}`

We thus see the answer as indicated/shown above

Hence, the correct answer is B
