Question

a graph of a function f is shown below. find f(-0.9).
select one:
a. -1.34
b. 2.641
c. 1
d. 2.1

Explanation:

Step1: Understand function notation

To find \( f(-0.9) \), we need the \( y \)-value of the function \( f \) when \( x = -0.9 \).

Step2: Locate \( x = -0.9 \) on the graph

From the graph, the point with \( x = -0.9 \) is labeled as \( (-0.9, 2.641) \). This means when \( x = -0.9 \), the corresponding \( y \)-value (which is \( f(-0.9) \)) is \( 2.641 \).

Answer:

B. 2.641
