Question

function notation:

1. find the value of f(2)
2. find the value of f(-1)

1)
2)

Explanation:

Step1: Find \( f(2) \)

To find \( f(2) \), we look at the graph of the function \( f(x) \). We find the point on the graph where \( x = 2 \). From the graph, when \( x = 2 \), we move vertically to the graph and then horizontally to the \( y \)-axis. The \( y \)-coordinate at \( x = 2 \) is 4. So \( f(2)=4 \).

Step2: Find \( f(-1) \)

To find \( f(-1) \), we look at the graph of the function \( f(x) \). We find the point on the graph where \( x=-1 \). From the graph, when \( x = -1 \), we move vertically to the graph and then horizontally to the \( y \)-axis. The \( y \)-coordinate at \( x=-1 \) is 1. So \( f(-1) = 1 \).

Answer:

1. \( 4 \)
2. \( 1 \)
