find the value of $f(-5)$. $y = f(x)$
find the value of $f(-5)$. $y = f(x)$
Answer
Explanation:
Step1: Understand the function notation
The notation ( f(-5) ) means we need to find the ( y - )value of the function ( y = f(x) ) when ( x=-5 ).
Step2: Locate ( x = - 5 ) on the graph
On the ( x - )axis, find the point ( x=-5 ). Then, move vertically until we intersect the graph of the function ( y = f(x) ).
Step3: Determine the corresponding ( y - )value
From the graph, when ( x = - 5 ), the ( y - )value (the value of the function at ( x=-5 )) is ( 3 ).
Answer:
(3)
